What I mean is that I can't get it to hang when I write different values to /sys/power/pm_test, as suggested in basic-pm-debugging.txt. It only hangs with the default value "none". Also, it doesn't matter if I put platform or shutdown in /sys/power/disk. It hangs anyway. I have noted, however, that it seems to hang much less frequently if I unload the Virtualbox modules. But I am not certain, and it does hang anyway after a while. I am in contact with Bojan Smojver who made some changes in the hibernate code for 3.2. He has given me further debugging hints, but he thinks that my error is due to memory corruption by i915. -- Pelle -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
