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.
