HDD READ/Timeout messages after 8.2 Upgrade

Fri Dec 31 02:10:21 UTC 2010

Greetings,

I replaced mobo/cpu/ram today and found the onboard nic not fully
recognized.  Since the kernel is just over a year old I decided to try a
system upgrade to see if the new hardware would get recognized.

I did a csup this afternoon, then a build world/kernel (kernel is default
but without debugging enabled).  After the reboot step, the system has
started spewing hdd errors such as:

ad6: TIMEOUT - READ retrying (1 retry left) LBA=575

The hardware is a 30g SSD for the O/S and system, and a 4x 2TB RAIDZ array
for all else.  Reverting to the old kernel has gotten the system back to
normal operation, but I would like to move forward.  I found a message from
someone experiencing a similar issue, but it was geli related and had
hardware errors in the message.

Above ad6 is the UFS SSD, all other drives are SATA RAIDZ spinning disks
(ad16 is non-raid spinning disk ZFS).  I have attached the dmesg from the
8.2 PRE-RELEASE kernel.

The physical hardware seems fine, particularly since it works on the 8.0
system.  Not sure how to troubleshoot and isolate the issue.

Any pointers?

TIA
