The problem was fixed by the following commit, present in all Ubuntu
releases: 625d7d351887 ("scsi: hpsa: correct ioaccel2 chaining").
Basically it was an access to a DMA non-mapped region, and was
restricted to non-RAID mode adapters due to the I/O path being
different.
Since it was fixed, no more work or debug is necessary here.
Cheers,
Guilherme
