Resume from Suspend does not work anymore

[Rainer Dorsch <ml@bokomoko.de>]

Hello,

since last weekend I have an issue on my jessie system with resume from 
suspend. The system seems to hang during resume: the screen does not get a 
signal, caps lock does not react, the SSH server does not come up, I see no 
entry in syslog.

I use pm-suspend to suspend. Resume from suspend worked for several years on 
that system. 

Thaw from hibernate still works flawless. 

I followed the procedure described in the Debian wiki, in particular I set the 
tests in /sys/power/pm_test and all of them successfully resume.

Any hint is welcome on how to get resume from suspend working again.

Many thanks,
Rainer
