I do not have problems when I hibernate from console. I conducted the following exercise: a script runs a 20-hibernate loop that saves dmesg output to individual files and pings my httpd server (on lo) after every resume. >From X, with the vanilla 2.6.39.4 kernel, I had 5 bad resumes out of 20 (the script continues though). My httpd server is pinged after all 20 resumes and my dmesg is saved to a file. So, even after the bad resumes, loopback networking and HD IO are functional. The five problem resumes all have a similar warning in dmesg (see below). I am copying Rafael Wysocki (since I can't seem to post to linux-pm@) and David Airlie (given the 'GPU lockup CP stall' message). [Please see thread https://lkml.org/lkml/2011/11/1/126 for complete history] The same loop test conducted either a) from console or b) from X after reversing commits 8ee294cd9def000 & 1d64b655dc083df encounters no problems (all 20 resumes succeed) and there are no GPU lockup messages in my saved dmesg output.
