[CentOS] Intermittent problem, likely disk IO related - mptscsih: ioc0: attempting task abort!

I think the panic is the consequence of drive write failure. So the actual
problem is before the panic call trace. I'd post the entire dmesg somewhere
wrap safe (either you mail agent or the forum is hard wrapping and is a
pain to read).

What do you get for
smartctl -x <dev>

In the meantime check or replace cables, usually it's the connectors that
are faulty not the cable itself. Or replace the drive.
