On hosts where the boot medium is BMC/IPMI virtual media, the ~2.8 GB
squashfs read often drops mid-transfer: rsync dies with "Input/output
error (5)", every file "has vanished", and live-boot moves the partial
RAM copy over the medium, ending the boot with "No supported filesystem
images found at /live".
Add hook 9013-toram-retry, which patches live-boot's 9990-toram-todisk.sh
so the whole-medium copy runs in a retry loop: up to 8 attempts with a
geometrically growing pause (15s -> 900s cap), unmounting/waiting/remounting
the medium between tries and honouring rsync's exit code (upstream ignores
it). rsync resumes from where it stopped, so a retry needing only the tail
finishes fast.
Verified against live-boot 1:20230131+deb12u1: substitution applies,
sh -n is clean, hook is idempotent.

The NVSwitch-detection fix (983f41a) was necessary but not sufficient on
HGX B200 (Kaytus KR9288-X3): ExecCondition now correctly runs fabricmanager,
but nvidia-fabricmanager-start.sh then aborts with "Kernel module ib_umad
has not been loaded" on this NVL5+ board, leaving the fabric stuck in
"In Progress" and cascading into failed dcgmi diag/NVBandwidth/NCCL/Validate
GPU SAT tasks (confirmed via support bundle 20260729-165331).
Neither nvidia-fabricmanager nor DCGM declare the NVLink5 support packages
as apt dependencies (checked against the cuda-repo Packages index directly):
ib_umad must be modprobed before FM starts, nvlsm (InfiniBand Subnet Manager)
is launched internally by FM's own start script once present, and DCGM
dlopens libnvidia-nscq at runtime for NVSwitch health monitoring.

bee.nvidia.mode=gsp-off loads the driver with NVreg_EnableGpuFirmware=0 and
skips nvidia-uvm/nvidia-modeset, so CUDA (nvbandwidth/dcgm/nccl) can't run —
and on Hopper H200 GSP is effectively mandatory anyway, so the mode is dead
weight in this test image. Remove it from every boot entry. fail-safe is now
bee.nvidia.mode=normal pci=realloc iommu=pt, so the GPUs come up with uvm and
the GPU test actually runs under iommu=pt (the point of the entry). All four
sources (grub.cfg + live.cfg.in templates, build.sh write_canonical_*) match.
The internal GSP auto-fallback in bee-nvidia-load (normal mode, GSP init
hangs >90s → retry with EnableGpuFirmware=0, then still load uvm) is left
intact — it serves converted SXM->PCIe cards on other test targets and keeps
CUDA working, unlike the removed explicit menu mode.

no-GUI is now just the normal entry minus the GUI: bee.gui=off with
bee.nvidia.mode=normal (drops the previous gsp-off/pci=realloc it had picked
up). fail-safe is now simply the GPU/PCIe-workaround boot —
bee.nvidia.mode=gsp-off pci=realloc iommu=pt over the standard base — instead
of the old noapic/nodma/nomce/nolapic/nosmp minimal mode, so it can actually
run GPU tests (nvbandwidth) to verify the iommu=pt half of the vendor fix.
Applied identically across all four sources (grub.cfg + live.cfg.in templates
and build.sh write_canonical_* generators).
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
The GRUB and isolinux menus (and their two sources of truth — the staged
templates and build.sh's write_canonical_* generators that rewrite the built
menu) had drifted: GRUB shipped a lean set, isolinux carried extra
display-debug entries (gsp-off, kms, kms-gsp-off) and lacked a WIPE entry in
the canonical writer. Collapse all four to one set:
normal, load-to-RAM (default), no-GUI/troubleshooting (gsp-off, pci=realloc),
fail-safe, WIPE ALL DISKS, Memory Test, + UEFI Firmware Settings (EFI only)
The fail-safe entry gains iommu=pt (AMD-Vi passthrough) — the OS-side half of
the vendor fix for the MSI CG480-S6053 cross-socket nvbandwidth reboot; ACS
can't be toggled from a stock-kernel cmdline so that stays a BIOS setting.
default stays index 1 = toram (config.cfg set default=1).
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
pci=realloc was forcing a full PCI resource reallocation on every default
and toram boot, added as a GPU BAR workaround for BIOS without Above 4G
Decoding. On a dense NVMe-backplane server it exhausted MMIO32 space and
silently dropped 4 of 6 NVMe controllers from the OS even though the BIOS
and lspci both saw them fine. It now only applies to the no-GUI/gsp-off
troubleshooting entry, alongside a bible-local ADR for the two prior
rounds of SAT/blackbox durability work.

v11.52's ISO build failed at chroot_install-packages:
datacenter-gpu-manager-4-cuda13 : Depends: datacenter-gpu-manager-4-core
(= 1:4.5.2-1) but 1:4.6.0-1 is to be installed
cuda13/proprietary/proprietary-cuda13 all declare an exact-version
dependency on datacenter-gpu-manager-4-core, but core itself was never
listed, so apt's solver picked the newest core in the repo (4.6.0-1)
for the transaction and then reported the pinned variants as unmet
instead of resolving everything to 4.5.2-1. Pin core explicitly so
there's no ambiguity for the solver.

590.48.01/DCGM 4.6.0-1 was never a deliberate compatibility choice — the
driver version traces back to a CDN 404 on the originally pinned
550.54.15 (commit 559fc29), and DCGM was bumped twice since purely
because NVIDIA pulled the previously-pinned core package from the repo
(6dee8f3, b2e177a). The 590 branch only has two point releases so far,
and its nvvs plugin fails dcgmi diag with "Detected driver major
version 0 is not between the required versions 346 and 2000" on H100 —
confirmed via a staging support bundle.
Switch to 580.126.20 / DCGM 4.5.2-1, the combo NVIDIA's own DGX OS 7.5.0
release notes validate for H100. Both packages confirmed present in the
NVIDIA CUDA debian12/x86_64 apt repo.

- storage: add jsonInt64 dual-format unmarshaler to handle lsblk output
change in util-linux 2.38 (LOG-SEC/PHY-SEC now emitted as JSON
integers, not quoted strings); fixes SATA disks invisible on Debian 12
- pcie: detect NVLink bridge mezzanine CX-7 cards (Mellanox x2, no host
net ifaces, DeviceName contains "NVLINK" in lspci -v) and mark them
with device_class="NVLinkBridge"; escalate PCIe link speed downgrade to
Critical for these cards (Gen3 on a fixed internal connector = hardware
fault, not a transient warning)
- pcie: cross-reference nvidia-smi topo to capture NVLink bond counts and
active status for all NVLink bridge cards
- packages: add infiniband-diags to ISO; provides ibstat required by
nvidia-fabricmanager-start.sh to enumerate IB devices before FM launch
(absence causes CUDA_ERROR_SYSTEM_NOT_READY)

Network: green if at least one interface has IPv4 (drop PARTIAL state).
Bee Services: treat inactive as OK — oneshot services (bee-sshsetup,
bee-preflight, bee-network, bee-audit, etc.) complete successfully and
exit to inactive; only failed is a real problem.
nvidia-fabricmanager: add ExecCondition=bee-check-nvswitch drop-in so
the service is silently skipped (inactive, not failed) on systems
without NVSwitch hardware (e.g. H200 NVL with direct NVLink, no
NVSwitch chips). bee-check-nvswitch detects NVSwitch via lspci
(vendor 10de, class 0680).
bee-nvidia.service: add ConditionPathExists=/usr/local/bin/bee-nvidia-load
so the unit is a no-op if somehow present in a non-nvidia build.
bee-boot-status: read /etc/bee-gpu-vendor and exclude bee-nvidia from
CRITICAL/ALL on non-nvidia builds, preventing boot hang if the unit
is unexpectedly present.

mksquashfs 4.5.1 (bookworm) writes a non-SQUASHFS_INVALID_BLK value for
xattr_id_table_start in the superblock even when -no-xattrs is passed, if
the source chroot contains POSIX ACL xattrs set by dpkg at install time.
Linux 6.1 squashfs driver then fails with "unable to read xattr id index
table" and refuses to mount the filesystem.
Strip all xattrs from the chroot via Python3 (already present) immediately
before mksquashfs runs. With an xattr-free source tree the resulting
squashfs is guaranteed to have SQUASHFS_INVALID_BLK in the xattr field.

GRUB's PNG reader (grub2 bookworm) fails to load bee-logo.png despite the
file being valid RGB 8-bit non-interlaced PNG with minimal chunks. Root
cause is a known fragility in GRUB's png.c; exact trigger is unknown.
Switch to uncompressed 24-bit TGA which bypasses the PNG parser entirely.
tga.mod is already present in the ISO (x86_64-efi/tga.mod).

IPMI hang fix (Lenovo XCC SR650 V3):
- Add pluggable ipmi_profile system with per-vendor timeouts and fruEarlyExit flag
- Lenovo profile: 90s FRU timeout, streaming early-exit stops after PSU blocks found
- collectFRUEarlyExit streams ipmitool fru print and kills process once PSU blocks
are followed by a non-PSU header (~6s instead of ~108s on 54-device FRU list)
- collectBMCFirmware and collectPSUs accept manufacturer and apply profile timeouts
VROC license detection:
- Detect VMD/VROC controller in PCIe list, run mdadm --detail-platform
- Parse "License:" line; store as snap.VROCLicense in HardwareSnapshot
Blackbox service fix:

- Move terminal_output gfxterm before insmod png / theme load so the
theme initialises in an active gfxterm context
- Remove echo ASCII art banner from grub.cfg — with gfxterm active and

Stability hardening (webui/app):
- readFileLimited(): защита от OOM при чтении audit JSON (100 MB),
component-status DB (10 MB) и лога задачи (50 MB)
- jobs.go: буферизованный лог задачи — один открытый fd на задачу
вместо open/write/close на каждую строку (устраняет тысячи syscall/сек
при GPU стресс-тестах)
- stability.go: экспоненциальный backoff в goRecoverLoop (2s→4s→…→60s),
сброс при успешном прогоне >30s, счётчик перезапусков в slog
- kill_workers.go: таймаут 5s на скан /proc, warn при срабатывании
- bee-web.service: MemoryMax=3G — OOM killer защищён
Build script:
- build.sh: удалён блок генерации grub-pc/grub.cfg + live.cfg.in —
мёртвый код с v8.25; grub-pc игнорируется live-build, а генерируемый
live.cfg.in перезаписывал правильный статический файл устаревшей
версией без tuning-параметров ядра и пунктов gsp-off/kms+gsp-off
- build.sh: dump_memtest_debug теперь логирует grub-efi/grub.cfg
вместо grub-pc/grub.cfg (было всегда "missing")
GRUB:
- live-theme/bee-logo.png: логотип пчелы 400×400px на чёрном фоне

Build uses --bootloaders "grub-efi,syslinux" so live-build reads

live-boot already uses rsync --progress when /bin/rsync exists; without
it the copy falls back to silent cp -a. Add rsync to the ISO package
list and install an initramfs-tools hook (bee-rsync) that copies the

rebuilds the initramfs so the change takes effect in the ISO's initrd.img.
