I'm getting a oops when mptsas.ko loads. It appears to be
in sas_host_setup() when dev_to_shost() is called.
I applied you're three patches to the current stream from last Friday, which
at that time was 2.6.13 + 2.6.13-git-9. Is that correct kernel
I should be on? Or should it be something else?
Here is the oops =>
