--- Comment #10 from Daniel Shafer <> ---
So I came across this same issue.  It was causing my server to reboot several
times a day due to kernel panics caused by this issue.  It happens with both
SAS9200 and 9300 controllers.  I have 8 x 10TB Seagate Iron Wolf NAS drives.

I wanted to mention that for me there was a resolution.  I added an Intel
Optane 900p 280GB drive and set that up for cache/l2arc and the problem
entirely disappeared.  My server ran for 20 days before I rebooted it last
night to perform an upgrade.

So, a workaround I believe would be is to add a cache drive to your ZFS pool.

The Intel Optane 900p is a highly recommended cache drive for ZFS pools.
