Oooh Oooh Oooh, pick me Mr Kotter!
I have seen this repeatedly, fought it and "apparently" beat it by upgrading my PSU.
I could reliably reproduce it by running a raid resync and issuing SMART queries
to the drives, but after a PSU upgrade it has gone away.
I have tried hard to reproduce it recently but I just can't get it to crash anymore.

I have a similar setup 4x SATA-TX4 cards and 15x 7Y250M0 drives. I'm thought it was actually
a bug, but as I can't reproduce it anymore it's making it a bit hard to track down.

Not much help, sorry.

Brad
