[CentOS] SCSI not settling???

Mon May 19 21:31:54 UTC 2014

Thanks for answering.

a) The workstation has:
- CPU E5-2687W
- 32 GB RAM (ECC)
- AMD FirePro V7900, original graphics card. (This happens with both the
AMD driver installed and not installed.)
- MegaRAID SAS 2008 controller configured for RAID1

I had a quad PCIe serial card in it as well, but I have removed it. No
change.

b) It's was not a fresh install, but it's been doing this only recently. It
started out with CentOS 6.3 or so in november 2012.

I saw some kernel oopses as well, I'm wondering whether the RAID controller
is going bad.
