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 22e0a697bfd5a86bd5c20d279bfffd131de6bb32]
