Same problem here: Absolutely random lockups, mostly when using Kontact / Akregator to read news, while trying to watch a page with embedded flash. Even more frequent, when I lock my screen, and go away... Then I have to do a hard reboot, since I cannot even switch to a VT.
Today I had 3 crashes all in all. The first one happened when I locked my screen and went away, the second one happened when I rebooted (it didn't even get to kdm, but crashed before...) and the third one was similar to the first one. I do get graphics errors (garbled images / faded screen) in contrast to others having reported this symptom. I should also add, that I have this behaviour mostly when using the Open Source driver (radeon module) in combination with a dual screen configuration. I.e. an external screen on my laptop. With the fglrx I am not able to configure the dual monitors correctly, so I cannot comment on that. There are no entries in /var/log/syslog referring to the crash, from what I can tell, but I've attached it to this post. if other logs are needed, please tell me what to upload to help the resolution of this really annoying bug. I have tried an updated radeon driver from http://ppa.launchpad.net/xorg-edgers/drivers-only/ubuntu and also I've tried an updated xserver from http://ppa.launchpad.net/ubuntu-x-swat/x-updates/ubuntu. I haven't tried a newer kernel as it's proposed here: http://ubuntuforums.org/showthread.php?t=1478787&page=97 (Post #964) Notebook is a HP Elitebook 6930p, with Kubuntu 10.04 64bit fully updated.
