Hello!
We have some Supermicro server based on X11SSH-F
All servers were installed half year ago and works under Fbsd 11.1. All server
have 4 HDD HGST HUS722T1TALA604
All of them works fine for this time with half year uptime.
Recently servers were upgraded to Fbsd 11.2 (self build 11.2-STABLE r335679
with default make.conf src.conf and GENERIC)
and after some time (all the time different, from 2 hours to 7 days) one or
some disks started timeout:

reboot (/sbin/shutdown -r or /sbin/reboot) does not solve the problem, disks
still timeout after boot. Only power off / power on solve problem for some
time. and after while it generate timeount
Servers were updated to latest bios available on Supermicro. No changes.

We use zfs on all servers, some servers are raidz1, some raid-10, with same
results
We use to use smartd on all servers, I tried to disable smartd. Looks like no
changes.
We already upgraded zpools to new features, it require remove features before
downgrade back to 11.1
