X-Debbugs-Cc: martin-eric.rac...@iki.fi
After upgrading an amd64 host from Bookworm to Trixie (2025-04-05 EEST), on
reboot, the host gets a kernel panic with:
initramfs unpacking failed invalid magic at start of compressed archive
The partition table:
sda1 vfat A28F-40DC
sda2 btrfs 960a40df-165b-408e-b47a-69df71aa7300
sda3 swap 02909177-67bb-4097-b1d8-8d18b07b521f
Booting from external media, I chroot myself in with:
sudo mount -o subvol=@rootfs /dev/sda2 /mnt/
sudo mount /dev/sda1 /mnt/boot/efi/
sudo mount --bind /proc/ /mnt/proc/
sudo mount --bind /dev/ /mnt/dev/
sudo mount --bind /dev/pts/ /mnt/dev/pts/
sudo mount --bind /sys/ /mnt/sys/
