Hm, I wonder if it's power management related or the device just goes
sideways for other reasons. The crashes are in accessing statistics
and the relevant function doesn't resume the device. But then again,
it could just be that stats reading is the most common control path
operation.

Hopefully the Intel team can help.

Would you be able to decode the stack trace? It may be helpful
to figure out which line of code this is:

  igc_update_stats+0x8a/0x6d0 [igc
