apport information ** Description changed:
I did a fresh install on a test laptop of 20.04 a while back, and after today's update, it no longer boots. Today's update included 2.31-0ubuntu6, but other 20.04 machines of mine also applied that and didn't fail, so I can't really be sure it's the cause. I also have zsys installed, and I noticed there are many snapshots of my datasets, and grub has a new menu entry about history. All that being said, I'm still troubleshooting and so far these are the facts: - partition layout: Device Start End Sectors Size Type /dev/sda1 2048 1050623 1048576 512M EFI System /dev/sda2 1050624 5244927 4194304 2G Linux swap /dev/sda3 5244928 9439231 4194304 2G Solaris boot /dev/sda4 9439232 937703054 928263823 442.6G Solaris root - - grub hangs when doing an ls on (hd0,gpt2), which is swap (?) - - grub hangs when doing an ld on (hd0,gpt4). + - grub hangs when doing an ls on (hd0,gpt2), which is swap + - grub hangs when doing an ls on (hd0,gpt4). - zfs-info (from grub's command line) on gpt3 is happy. It identifies it as bpool - zfs-info on gpt4 complains it has unsupported features, but does not hang When booting the system, it hangs right after I select a menu entry in grub, regardless of which one. Even the history ones from zfs hang, although I didn't try all. It looks just like the hang on the simple ls command. This is grub2 2.04-1ubuntu22, and zsys 0.4.1. I'll see if I can run collect from inside the mounted system in a chroot from a rescue image, and attach info to this log. ** Tags added: apport-collected focal ** Description changed: I did a fresh install on a test laptop of 20.04 a while back, and after today's update, it no longer boots.
