Describe the problem you're observing

I have a pool that started showing lots of errors and I traced that to a bad RAM stick. After running scrub, the pool shows the following:

> sudo zpool status tank -v
  pool: tank
 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:

        tank/vm-102-disk-1:<0x1>

In this pool I can read and write all the files in the tank dataset. The only dataset giving issues is the vm-102-disk-1.

Now, I run sudo zfs destroy tank/vm-102-disk-1 and the command either seems to succeed or sometimes just hangs forever. In both cases, the dataset is never destroyed, and a kernel panic is printed in the kernel log.

For now, my solution has been to create a new pool and copy all the data from my corrupted pool to the new one. I've also replaced my RAM with ECC RAM (lesson learned). Soon I plan to completely remove the pool, but I wanted to submit an issue just in case.

Describe how to reproduce the problem

Not sure TBF... :/

Include any warning/errors/backtraces from the system logs
