Package: grub-efi-riscv64
Version: 2.14-1
Severity: grave
Justification: renders package unusable
X-Debbugs-Cc: debian-riscv at lists.debian.org
User: debian-riscv at lists.debian.org
Usertags: riscv64
Dear maintainers,
When using grub version 2.14-1 on riscv64, it fails to boot after
selecting the kernel to boot with the following error:
| error: ../../../grub-core/fs/fshelp.c:find_file:260:file `/boot/grub/riscv64-efi/efi_uga.mod' not found.
| Loading Linux 6.18.8+deb14-riscv64 ...
| Loading initial ramdisk ...
|
| Press any key to continue...
After pressing a key, the boot continues, but that breaks automatic
reboot and require having a keyboard/screen or a serial console.
It seems that in the previous version loaded all_video.mod, while the
new version loads both efi_gop.mod and efi_uga.mod. According to the
Makefile, it seems the latter is x86 specific, and thus should not be
loaded on riscv64. Manually removing it from the config file fixes the
issue.
I believe the issue also affects other non-x86 architectures, but I
can't easily check at the moment.
Regards
Aurelien
