This happens 1 time per week it seems, I can fix it manually by doing Alt-R and marking all drives as online again. But essentially we lose the RAID each week because of these sequence errors and then we need to reboot and fix the RAID card, then its fine for a week.

Here is the relevant info:

Report it to the maintainer , address in the driver. From memory I believe this occurs if you use drives with bugs. There is a Mylex list of 'approved' drives and if you stray from it so be it. I dont think its a Linux thing
