In KDE when I pull the power cord, the system instantly freezes - completely, leaving no helpful traces of the cause in syslog or pm-powersave.log. It does not happen w/o a running KDE session or when I switch to Unity or XFCE. Hence, I suspect KDE triggering the bug. Googling for "power unplug crash linux kernel" yields a bunch of somewhat similiar issues, but those all seem slightly diffrent from what I see. In fact, I have had the/an "unplug crash issue" before like a year or so ago. Somehow it vanished, and now it is back again, so this could be a kernel regression. --- ApportVersion: 2.12.5-0ubuntu2.1 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: deas 6090 F.... pulseaudio DistroRelease: Ubuntu 13.10 EcryptfsInUse: Yes HibernationDevice: RESUME=UUID=901a5939-36e9-4493-9f9d-68a6fea3613e InstallationDate: Installed on 2011-03-07 (1009 days ago) InstallationMedia: Kubuntu 10.10 "Maverick Meerkat" - Release amd64 (20101008) MachineType: Dell Inc.
