I have searched the webs but have not found this issue you described. Can you point me to info on kernel lore or another place where this is documented?
I dont see the similar problem I saw before that got me to use use power_scheme=1 to prevent it from going to sleep, but the driver page itself suggests this setting for system noise, etc.
AFAIK most network cards accept that noise exists and use a watchdog, but (if that is even the problem) this one either doesn't or can't recover for some reason.
(With the workaround it still hangs occasionally but not almost every time its been suspended.)
