Well, lets not rush this in till all the panics are fix'd.
Here's one of the issues:
Try compile the driver as a module. Load -> unload -> load -> panic.
I suspect that in the scsi_transport_sas.c, the sas_remove_host is
not cleaning up the wide ports. My setup is one controller
with one expander attached. No end devices.
Here is my trace:
