Hi,
4a865905f685eaefaedf6ade362323dc52aa703b
(PCI PM: Make pci_set_power_state() handle devices with no PM support)
breaks e1000 after being kexec'ed. These reverts fix the problem:
Revert "PCI PM: Make pci_set_power_state() handle devices with no PM
support"
Revert "PCI PM: Introduce __pci_[start|complete]_power_transition()
(rev. 2)"
I reverted the second one just for an easy revert of the former one,
which is actually the culprit.
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

Include this output when contacting your support provider.
This is not a software error! Something bad happened to your hardware or
EEPROM image. Ignoring this problem could result in further problems,
possibly loss of data, corruption or system hangs!
The MAC Address will be reset to 00:00:00:00:00:00, which is invalid
and requires you to set the proper MAC address manually before continuing
to enable this network device.
Please inspect the EEPROM dump and report the issue to your hardware vendor
or Intel Customer Support.
