Can you find time to try it without smartd active ?
You report running a uni-processor system, and I have only
seen PIO problems with (fast) SMP systems in my testing,
but I am forming the opinion that libata-PIO functions
are in need of a minor overhaul.
I have seen issues where port activity monopolised
data-paths/arbitration inside chipsets such that the
PIO operations would appear to time out. Since you're
doing a raid rebuild, perhaps the I/O load is causing
something similar to occur.
