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.
