Description Menanteau Guy 2021-03-11 14:49:46 UTC 
I am not able to install a fresh Fedora 34 on a qemu running on a P9 powerpc.
Error reported is:
error: ../../grub-core/loader/powerpc/ieee1275/linux.c:249:couldn't claim memory.

I tried with Fedora-Server-dvd-ppc64le-34-20210310.n.0.iso but it seems is was already there for older iso.

How reproducible:
On a powerpc P9, run the following qemu command.
/usr/bin/qemu-system-ppc64 -vga std -m 4096 -netdev user,id=qanet0 -device virtio-net,netdev=qanet0,mac=52:54:00:12:34:56 -device virtio-scsi-pci,id=scsi0 -device virtio-blk,drive=hd1,serial=1 -drive file=hd1.qcow2,cache=unsafe,if=none,id=hd1,format=qcow2 -drive media=cdrom,if=none,id=cd0,format=raw,file=Fedora-Server-dvd-ppc64le-34-20210310.n.0.iso -device scsi-cd,drive=cd0,bus=scsi0.0 -smp 1 -enable-kvm -no-shutdown -S -nographic -nodefaults -monitor stdio -serial pty -boot d

at boot grub menu, select:
Install Fedora 34 (64-bit kernel) 

Actual results:
error: ../../grub-core/loader/powerpc/ieee1275/linux.c:249:couldn't claim
memory.
error: ../../grub-core/loader/powerpc/ieee1275/linux.c:347:you need to load the
kernel first.

Press any key to continue...

Expected results:
Fedora installation complete


installed packages on host:
kernel.ppc64le                     5.10.11-100.fc32
qemu.ppc64le                       2:4.2.1-1.fc32

Note that it is working fine on a P8 powerpc host with same kernel and qemu version.
Comment 1 Javier Martinez Canillas 2021-03-11 17:20:18 UTC 
This should be fixed by grub2-2.04-36 but due the Beta Freeze the version
in the install media is still grub2-2.04-35.

I'll requesting a Freeze Exception for this bug.
Comment 2 Fedora Blocker Bugs Application 2021-03-11 17:23:38 UTC 
Proposed as a Blocker for 34-beta by Fedora user javierm using the blocker tracking app because:

 Some ppc64le machines fail to boot due GRUB not being able to allocate memory.
Comment 3 Ben Cotton 2021-03-11 19:03:22 UTC 
From today's Go/No-Go meeting:

RejectedBlocker(Beta), AcceptedFE(Beta) - ppc64le is not a blocking architecture, but this is worth fixing if we can

What is the relative change of grub2-2.04-36 that is supposed to solve this bug described as a P9 specific failure ?
Comment 5 Javier Martinez Canillas 2021-06-11 00:24:56 UTC 
This should had been fixed by now, if the issue persists feel free to re-open.
