I have re-run X since. I have attached the old log file. However, the crash doesn't allow ssh access and my HD is not unmounted cleanly. An e2fsck is run to repair the disk. The process list I attached is also typical. The crash happens when I exit X (returning to the tty shell where I typed "startx &"). I also get the following messages when switching tty, Aug 10 22:49:59 pvr kernel: intelfb: ring buffer : space: 11888 wanted 65472 Aug 10 22:49:59 pvr kernel: intelfb: lockup - turning off hardware acceleration The "/usr/share/bug/xserver-xorg/script" also seems to say this. I am pretty sure that the problem is an interaction between the framebuffer tty and X-windows. I had some lockups with mplayer forced to run in framebuffer mode when played in X-windows. This was prior to getting the testing xserver-xorg-intel package which allows HDTV playback with the "xv" device. I seem to recall a lock when switching tty's via "control-alt-Fn", but I only had this when running idesk. Note, I do get this crash when not using idesk. The problem seems worse when using idesk, but this maybe just do to a shift in memory or something. There is no IP access (not even ICMP). The "magic sys req" also does not work. Thanks, Bill Pringlemeir.
