This can't be a SCSI issue because the problem was caused before SCSI was entered. Looking at the backtrace (all functions listed as unreliable, sigh) this is either a deadline scheduler problem (less likely) or an md_raid one (more likely). Let's start with what was the mdraid configuration and condition of the filesystem being mounted? I've added linux-raid to the cc list so they can chime in for more details.
