Comment 11 for bug 232017

I can reliably oops the 2.6.24-server kernel with my AAR-2410SA in 4x500GB RAID 1+0 mode, any real IO for instance via NFS or iSCSI will cause the oops. Increasing the swiotlb causes the system to be unbootable and results in almost instant oops. I built a vanilla 2.6.26.2 kernel and experienced the same error. I have another box running feisty and 2.6.20-16-server in RAID 5 with lots of consistent IO and never experience a problem. Below is the lspci -vv output for the card and attached is the most recent trace with linux-image-debug-server, I'll now also try with -generic
