Anyone still having issues on 855 hardware, please have a look at LP Bug #108056

I'm put online a .deb (and sources etc..) which has debug code for anyone still having issues:
http://www2.eng.cam.ac.uk/~pcjc2/ubuntu/debug/
http://www2.eng.cam.ac.uk/~pcjc2/ubuntu/debug/xserver-xorg-video-intel_2.1.1-0ubuntu9~pcjc2.tst_i386.deb

I've added calls to sync() after every log messge I added, so _hopefully_ some of this will make it to disk if the machine hard-locks, although hardware write-caching on the disk may put pay to that.

You might try disabling that before VT switching with:
hdparm -W 0 /dev/HARD_DRIVE

Those who know how to attach strace from a remote machine will be able to see everything even if the machine locks.

I'd be interested to see log output from this for anyone who still has failures. Please post to LP #108056 if its on 855 hardware though, as I'd like to think this bug is heading towards being closed.
