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
