Package: zfsutils-linux
Version: 0.7.13-1
Severity: important
Dear Maintainer,
When doing a scrub of my ZFS filesystem with 4.19 I get warnings of hung
processes, followed by the system going catatonic. This happens within
seconds of starting the scrub.
When doing the same operation after reloading into 4.9 everything works
out just fine.
I've logged the kernel logs to a ext4 partition to get the logs below.
Open to do limited testing as I need to be physically close to the machine to
reboot it :/.
Best regards, Peter

Closing this bug as too many days & versions have been passed.
There are multiple reports related to l2arc_feed stuck [1][2][3]. But none
seems the same.
We have to admit that many similar issues exist in zfs. :-(
