Just a quick FYI for other people in a similar situation… We were recently testing Multipath under OpenSuSE via an LSI SAS controller that uses the mptsas driver. It would fail over to an alternate path, but would give a kernel oops and then would have to be hard booted before it would fail back. It looks to be a bug in the mptsas driver in the OpenSuSE kernel, and I was able to resolve it by building 22.214.171.124.
I hadn't found mention of this specific issue on google, but I did find that there have been a lot of changes to the mptsas driver. The oopses are gone after the upgrade to this new kernel.comments powered by Disqus
