RecovComm: Communications between device and host temporarily lost, but 
Persist: Persistent communication or data integrity error
HostInt: Host bus adapter internal error
PHYRdyChg: PhyRdy signal changed state
10B8B: 10b to 8b decoding error occurred

Sounds like the drive and the controller are unhappy with each other, or 
there's some kind of communications or hardware problem. Not likely a 
kernel issue.

It's unclear if limiting to 1.5 Gbps would help, you could try it and see..
