Re: [e1000e] e86e383f28: suspend-stress.fail

[Zhang Rui]

Hi, all,

This patch has been shipped in 5.8-rc1 with its upstream commit id
0c80cdbf3320. And we observed big drop of suspend quality.

Previously, we have run into this "e1000e Hardware Error" issue,
occasionally. But now, on a NUC I have, system suspend-to-mem fails within 10 suspend  cycles in most cases, but won't work again until a reboot.
https://bugzilla.kernel.org/show_bug.cgi?id=205015

IMO, this is a regression, and we need to find a way to fix it.

thanks,
rui
