mount stuck during journal replay after an unclean shutdown

[g2p]

This is for /tmp, which should be a mostly empty filesystem. Shutdown takes a long time for unclear reasons (may not be related to bcachefs), and I just reset the machine. I'm on d11e1164d85f6d6e08942edc0f5d14f9e9c6a8a0 with the usual rebasing over linus/master (e091caf99f3a5006c95baec24330bac6f7f17193). The following hangs (during journal replay?): mount -t bcachefs -o verbose,noatime /dev/mapper/... /tmp

In dmesg I have:

[g2p]

In dev-0/alloc_debug, free at zero seems strange. Whereas user at zero seems correct (I guess systemd clears the fs before shutdown).

[koverstreet]

Try mounting with -o fsck,fix_errors; that looks like an upgrade from 1.7 that didn't regenerate accounting info

[g2p]

fsck,fix_errors still gets stuck. The backtrace from dmesg is almost identical, just a difference around bch2_journal_replay_key.

Should I send you the filesystem dump? Or just drop/recreate the fs, in this case there's no useful data I would like to keep.

(Probably a botched accounting migration issue as you say, as I used /tmp to bisect #707. I'll send a metadata dump on request)

[g2p]

This one did journal replay and got stuck within check_allocations with a lockdep warning (decode_stacktrace will come after a reboot):
