Can you just try to revert the changes in pci_raw_set_power_state() and check if that has any effect (it shouldn't)? > The symptoms: > e1000 0000:02:01.0: enabling device (0000 -> 0003) > e1000 0000:02:01.0: PCI INT A -> Link[LNKA] -> GSI 11 (level, low) -> IRQ 11 > e1000 0000:02:01.0: setting latency timer to 64 > e1000: 0000:02:01.0: e1000_probe: The EEPROM Checksum Is Not Valid > Switched to high resolution mode on CPU 0 > /*********************/ > Current EEPROM Checksum : 0xffff > Calculated : 0xbaf9 > Offset Values > ======== ====== > 00000000: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff > 00000010: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff > 00000020: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff > 00000030: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff > 00000040: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff > 00000050: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff > 00000060: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff > 00000070: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff > Include this output when contacting your support provider. > This is not a software error!

What happens if you remove just the /* Check if we're already there */ if (dev->current_state == state) return 0; part from pci_set_power_state()?
