e1000e hardware unit hang after s2idle
May 06 15:34:49 ubuntu kernel: e1000e 0000:00:1f.6 enp0s31f6: Detected Hardware Unit Hang: TDH <1> TDT <5> next_to_use <5> next_to_clean <1> buffer_info[next_to_clean]: time_stamp <1000587f0> next_to_watch <1> jiffies <1000589c0> next_to_watch.status <0> MAC Status <40080283> PHY Status <796d> PHY 1000BASE-T Status <3800> PHY Extended Status <3000> PCI Status <10>
[Test]
Verified on the target machine, and confirmed the issue is gone.
[Where problems could occur]
The impact is low, it keeps the GPT clock enabled for CSME when e1000e_pm_resume() is called. I can't see this may introduce any regression.
