System information

I get this error on the disk containing the root partition
This happens on recent kernels, but not on the 2.6.32.61 kernel.
The code generating these messages is however identical in 2.6.32.61 and newer kernels.
This doesn't especially happen when the system is under high load.

This happens on both our production and stand-by server. Production server was switched back to 2.6.32.61.

Attached file contains system information of the stand-by server running kernel 3.14.0 (cpuinfo.txt  lspci.txt  meminfo.txt  proc_scsi_scsi.txt  ver_linux.txt).

I can provide more info and perform tests if needed.
