Since some time I have the following behaviour:
I work on my laptop on battery some time. Plug in the power, and system freezes. (Clicking mouse/keyboard - no reaction).
Once I unplug the power; the system unfreezes (and it has "queued" the meanwhile clicks and actions which get performed upon power unplug.)

/var/log/messages shows the following:
      Code:

Dec 19 00:18:47 siddie-new kernel: [41499.279659] keyboard: can't emulate rawmode for keycode 240
Dec 19 00:18:47 siddie-new kernel: [41499.279684] keyboard: can't emulate rawmode for keycode 240
Dec 19 00:18:54 siddie-new kernel: [41506.607768] EXT4-fs (sda6): re-mounted. Opts: errors=remount-ro,commit=600
Dec 19 00:18:54 siddie-new kernel: [41506.656956] keyboard: can't emulate rawmode for keycode 240
Dec 19 00:18:54 siddie-new kernel: [41506.656981] keyboard: can't emulate rawmode for keycode 240



It is not easily reproducible but happens frequently (since some time - i.e. maybe with some of the last kernels, can not however precisely say which one - current kernel is 3.1-5.slh.3-aptosid-amd64 ).
