Describe the problem you're observing
I keep getting false permanent errors intermittently. I.e.:
$ sudo zpool status -v
pool: thing
state: ONLINE
status: One or more devices has experienced an error resulting in data
corruption. Applications may be affected.
action: Restore the file in question if possible. Otherwise restore the
entire pool from backup.

errors: Permanent errors have been detected in the following files:
As far as I can tell, all the files in the list of files are valid and not corrupt, every single time. But it's a tedious process to clear the error list. Perhaps if this is not a bug, we can change this to a feature request for a zfs command to re-check all files in the error list.
Describe how to reproduce the problem
I haven't figured out a way to trigger it. Sometimes it happens multiple times per day, sometimes it doesn't happen for weeks.
Include any warning/errors/backtraces from the system logs
Oh shoot! Now that I am actually looking for logs, I see this scary warning! 😮

This is scary. I don't remember being warned in the GUI. I have been staying at this kernel for video hardware reasons. I will see if I can get a kernel that works with the hardware but also doesn't warn me about ZFS.
Still, the files in the errors are not lost data. Judging from #18488 the message is a precaution and is probably not related to actual bugs, if I understand correctly.
