I believe these are: self build :Marvell 6480 Thecus: Marvell Technology Group Ltd. MV88SX6081 8-port SATA II PCI-X Controller (rev 09) The problem that I have personally experienced was on (and before) the 12 December 2011 and (to my entirely untrained eye) consisted of one of more of the drives posting unplug and plug messages. I suspect this later resulted in a degraded array and a resync. I am not a Linux expert so I don't know what else to include. As an aside, are there any recommendations regarding sanitising kernel/dmesg logs prior to posting as I have a copy of the logs which contain the zgrep's of 'mvsas' and resultant errors and would be happy to post them if desired. The reason for this is that my Thecus (Linux 2.6.13N5200 #135 Mon May 24 17:46:32 CST 2010 i686 unknown) has gone out of support and I am looking at installing Ubuntu server on it and I don't want to do this is the controller issues are still present. I've not noticed any issues with the 2.6.13 kernel that the unit is on but the logs are heavily sanitised by Thecus so I can't tell. I am considering going for the Ubuntu 10.04 LTS Server release but I don't know what, if any, impact doing updates will have on the mvsas driver. Thank you for your help and I'm sorry for the lack of information. regards Simon
