We have 24 1TB Seagate harddisks connected in a RAID 60 to the adaptec controller, and a Tandberg T80 with two IBM Ultrium-HH4 tape drives connected to the LSI controller. The system is installed on an LVM volume within the RAID 60. The data corruption occurs when we try to boot 2.6.32-rc6, we get write errors and the boot process stops somewhere. So, it seems the data corruption is related _only_ with the Adaptec Controller, the RAID array or the harddisks. >> Finally, the real problem here is Bug 14579 that is about the systems >> problems when using the tape library. >> >> >From dmesg log I can figure out 3.04.07 is mpt fusion driver version. >> >Please update LSI driver using latest upstream driver version 3.04.13. >> And see what a result is. >> >> Thanks for the pointer.

But there lies the problem: Unless we can fix the Adaptec-Bug first (or confirm it is a hardware issue), we can't boot 2.6.32-rc on that machine to test the new LSI driver version. Is it easily possible to backport/include the mptfusion in 2.6.30?
