Yeah, well, turns out it didn't help anyway: [30490.846160] ACPI: Waking up from system sleep state S4 [30491.371450] HDA Intel 0000:00:08.0: restoring config space at offset 0x1 (was 0xb00006, writing 0xb00002) [30491.379411] forcedeth 0000:00:0a.0: restoring config space at offset 0x1 (was 0xb00003, writing 0xb00007) [30491.387352] ahci 0000:00:0b.0: restoring config space at offset 0x1 (was 0xb00403, writing 0xb00407) [30511.970606] pci 0000:00:03.2: PME# disabled The problem doesn't always happen.
