Package: grub-efi-riscv64-unsigned User: debian-ri...@lists.debian.org Usertags: riscv64 X-Debbugs-Cc: debian-ri...@lists.debian.org X-Debbugs-Cc: rabenda...@gmail.com Version: 2.12-8 Severity: normal Tags: upstream
Dear Maintainer, Illegal instructions will occur when debian riscv64 iso boots to grub.efi. Because grub uses the rdcycle instruction. Upstream[1] has fixed this issue and hopes to backport to 2.12.
