Title:
grub stuck on loading kernel, fails to ls zfs and swap partitions
To manage
The ZSys part of the issue (garbage collection not being agressive
enough when reaching bpool or rpool size limit) is handled on bug
#1876334.
I’ll just add a reference there and remove the ZSys task instead of
dupping so that the foundation team can handle the grub side of it.
** No longer
There is definitely a bug in grub here if it's hanging, but it seems
like zsys should be doing a better job of garbage collecting old
snapshots instead of letting this list grow to the point that it breaks
grub.

Title:
grub stuck on loading kernel, fails to ls zfs and swap
I removed all the zsys snapshots (had about 17), and then it booted
fine. grub must have some trouble when there are many zfs snapshots. I
tried removing only the last and rebooted, and it still wouldn't boot,
but I didn't run update-grub, nor updated the initramfs, nor reinstalled
grub, in that
I just ran dist-upgrade, fetched the latest focal (not proposed)
updated, ran update-grub, grub-install, same thing.

Another important bit of information is that rpool (NOT bpool) has zfs
encryption enabled. This was working just fine: I got a prompt for the
password during boot (graphical even). But now the kernel doesn't even
load.

If I select advanced, then safe mode, all I see is
Loading Linux 5.4.0-14-generic ...
I've left it at that for about 30min, nothing changes. ctrl-alt-del also
doesn't work, nor does sysrq boot.
