Public bug reported:
I am currently in the process of ripping and encoding all my DVDs; as
such I have my computer on and working constantly. At some point it will
freeze, but only after working for many hours. (5-30 hours)
This has occurred when encoding h.264 multi-threaded in ffmpeg,
extracting the contents of 3 DVDs simultaneously, or even just using the
computer after performing those sorts of activities. It occurs when
using KDE, Gnome or Fluxbox as window manager. I should also mention
that I use the system as a casual Samba server too, but it never freezes
when any clients are connected.
Parts of the user interface will freeze first, and then after a minute
the rest of the computer (including mouse and emergency key
combinations). No new programs can be opened while the system is
partially frozen. Attempting to switch to a virtual terminal will
immediately lock up the whole system, as will pressing Alt-SysRq-R. Only
once has this freeze resulted in the keyboard lights flashing, and it's
rare to get any kernel messages regarding it, making me believe that the
kernel is stopping before being able to sync or actually run the panic
function.

-------
I have seen the traceback on one previous occasion, where Plasma was listed as
the running process. Of course, I've had the crash when not running KDE. I have
established that the crash is not related to thermal issues or high memory use,
and I do not get the crash unless the machine has been on for some hours.
I am running Ubuntu 8.10 64-bit, fully updated from the Proposed
repository except for the kernel, which is "2.6.27-11-generic #1 SMP Fri
Dec 19 16:29:35 UTC 2008 x86_64 GNU/Linux"
