Public bug reported:
Customer is seeing this:
we still see Linux EFI stub failed to boot with this error:
EFI stub: Booting Linux Kernel...
EFI stub: Using DTB from configuration table
EFI stub: Exiting boot services...
EFI stub: ERROR: Exit boot services failed.
This failure won't occur when we add the kernel commandline parameter
efi=disable_early_pci_dma
THe linux-nvidia kernel has a SAUCE patch to increment this value from 8
to 16 but 16 is not enough for this customer. There is an official
upstream patch that will bump this value to 32.
