[Bug 554398] Re: Lucid crash on heavy DB i/o (mvsas?)

[Peter Funk]

Last week I wrote that a SuperMicro 8-Port SATA Controller doesn't work with Ubuntu 10.04 64 Bit.
We got error messages from mv_sas.c driver and the disks became unaccessible.  
The same happens with OpenSuSE 11.2 so I assume it is a general driver problem. 

Today we tested the same hardware using a CentOS 5.4 x86_64 LiveCD to check whether this
might really be regression as already asked by Richard Weait on 2010-04-05.

Since it is difficult to test with real applications using a live cd, I tested copying a bunch of
huge TIF image files from one directory to another repeatedly.  This ran without problems.
(RAID10 build out of 8 SATA disks, filesystem XFS).

So in the moment I've to assume there is really a regression in the mvsas driver module.
CentOS 5.4 contains mvsas version 0.5.4
whereas both Ubuntu Lucid and OpenSuSE 11.2 contain mvsas version 0.8.2
We tested the 32-Bit Desktop version also: It also doesn't work.

Any suggestions how I should proceed to narrow this down any further?
