Type: Direct-Access ANSI SCSI revision: 05 [7.7.] Other information that might be relevant to the problem (please look in /proc and include all information that you think to be relevant): [X.] Other notes, patches, fixes, workarounds: I think the problem is the H700 controller in combination with the megasas-driver. We have a lot more systems running 2.6.33.2 and only the servers with the H700 controller are giving this problem. Also after some sime (after the scanning and oops) we experience user space freezes. I tried 2.6.34 and give the same problem, only not the 'scanning-loop', just 1 'scanning-line'. It's on a production server so I didn't test 2.6.35, can't reproduce it on a test machine.
