Hmmm. You might have a hardware issue. OTOH, you can try seeing if you have a BIOS option to disable PCIE error logging.

is it one of them?:

If so, turning it off may fix your hangs since as the act of writing the entry to the system event log can take several hundred milliseconds on some machines causing a hang of sorts. If you still get hangs with the option turned off then it seems you have some sort of hardware issue, possibly in the mfi(4) adapter or mainboard.
