Sorry, no idea. The assert is about a memory allocation failure (you can
check the source code at the location captured in the assert):
Status = AllocateLegacyMemory (
AllocateAddress,
CONVENTIONAL_MEMORY_TOP - MemorySize,
EFI_SIZE_TO_PAGES (MemorySize),
&MemoryAddress
);
ASSERT_EFI_ERROR (Status);
I don't know why it fails.
Perhaps you can experiment with older SeaBIOS releases and narrow it
down a little. (You could also experiment with OVMF builds at different
git commits, but I don't readily recall anything that could cause this.)
I'm adding David, Kevin and Gerd to the CC list.
Thanks
Laszlo
