Hi Adam,

Thanks for responding!

LSI just got back to me on a second case, their latest beta firmware:
http://www.lsi.com/DistributionSystem/AssetDocument/readme.txt

SCR 2196:  Unexpected controller soft resets
Fixed an issue with regards to  deferral of write and read commands to 
help eliminate unexpected soft resets.

Well well!

Plan of action:

1. See if the error recurs without 'nobarrier' - only because there are 
some threads about problems when this is enabled on 3ware controllers.

2. LSI recommended I disconnect/replace my BBU module, I already did once 
before, ~$120, so the next step I will apply their latest Beta firmware.

3. If it STILL does it, I can increase the timeout, HOWEVER, when I see 
this, I/O on the system, everything locks up for 60-120-180-360 seconds 
and then it comes back after it resets the controller.  The weird thing is 
this controller is only for a /data volume and not the root filesystem. 
The root filesystem is on a separate RAID-1 4 port card (also w/BBU).

If you google that exact error, there is very little information, if I 
find something that works, I'll update the list so others have something 
to point to when they see this problem.

Justin.
