I'm trying to load PCMemTest on a UEFI Fedora system.
https://github.com/martinwhitaker/pcmemtest
After placing the binary on the ESP, I'm able to create an entry with
efibootmgr to load it directly from the UEFI boot menu, and it works as
expected, so I'm certain that the binary is "good".
However, I haven't been able to load the program from GRUB
successfully. The program's documentation says that it supports the
UEFI handover boot protocol, and I've tried loading it using "linux
/<path>/pcmemtest.efi", which doesn't seem to do anything. As far as I
can tell, the system halts. I've also tried chainloading the binary,
and when that entry is selected, GRUB immediately returns to its menu.
Does anyone have any basic hints for me at this point, either things
that I should try, or anything that might tell me what's happening after
the handover?
