Hmmm! So you were in the mpt/fusion driver when you ran out
of SWIOTLB space. That's an area where we both have the same
hardware ... and since it booted for me, it means that the
driver isn't totally broken.

I'm totally ignorant of what goes on inside this driver though.
You have more "ioc's" than I do. I only see messages from mpt
bringing up ioc0 & ioc1. Your boot_log also has ioc2 (which is
where you crash). Here's the sdiff(1) output comparing the MPT
part of your boot log with my successful boot of the same kernel
and config (your log is the one on the left). Maybe some MPT/Fusion
expert can spot something important in this bit?
