I kicked off a ZFS scrub and let it run overnight for about 10 hours. I noticed multiple kernel messages in dmesg the next morning and the scrub never finished. Reproducible: Didn't try Steps to Reproduce: 1. zpool scrub rpool 2. <wait> 3. Watch dmesg Actual Results: See attached log. Expected Results: No kernel messages should appear in dmesg.

As per our discussion in IRC, this report has been refiled upstream. This report is in no way Gentoo-specific and as far as I know, it is the first of its kind. My own time to work on this is incredibly limited, so it would be far better to combine resources with upstream.
