I found this error in dmesg after the last boot.
Immediately before this message I see the mount of an external software RAID array of eSATA disks. The filesystem mounts and fscks run with no issue - this is the only indication of problem. This occurred after the last kernel update and reboot.
This is Dell PE850 hardware with a non-dell Silicon Image Port Multiplier compatible PCIe eSATA card installed.
Can anyone hit me with a clue on this?

My google-fu is not that strong, but it looks like this has been a known issue for a long time.
