Downgrading these libraries did not fix it for me. One canary is to look at the state of the updatedb.mlocate process which goes into live hang as it hits the file that is currently faulty. Thus for example:
2728 ? DNs 0:01 /usr/bin/updatedb.mlocate Using lsof one can find out which is the faulty file but, if you try to ls the directory with the file in, then you terminal live hangs. And if you try to delete the directory containing the faulty file, then that silently fails, leaving the directory and the live hang should you try to read it. It's said that this bug relates to 1906476 and via that to https://github.com/openzfs/zfs/issues/11474 but I think I have that one fixed with zfs_recover=1. But the syslog message is very similar: Aug 11 10:13:45 silmh9 kernel: [ 242.531205] INFO: task updatedb.mlocat:2728 blocked for more than 120 seconds.
