Describe the problem you're observing
One specific snapshot hangs when it is being automatically deleted by zfs-auto-snapshots or when being manually deleted by zfs destroy
Describe how to reproduce the problem
I don't know the specifics but this is the only snapshot that it is considerably bigger thatn the usual daily snapshots that I take on my laptop, keeping the last 7 of them.
Whenever I try to delete it, the PANIC: zfs: rt={spa=zdublin vdev_guid=11798591573025218853 ms_id=115 ms_defer}: adding segment (offset=1cc2ec4b000 size=8000) overlapping with existing one (offset=1cc2ec4b000 size=8000) message is provided, indicating "overlapping offsets"
Include any warning/errors/backtraces from the system logs
Before deleting the snapshot:
zfs list -t snapshot
