Justin,
This just means the firmware didn't complete an ioctl in 60 seconds.
Can try changing this define in 3w-9xxx.h:
#define TW_IOCTL_CHRDEV_TIMEOUT 60 /* 60 seconds */
to 90 or 120 seconds to see if that fixes your issue?
Thanks,

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.
