I have similar symptoms with my Kubuntu 7.04. Didn't have these problems at all with Edgy. Today I've already had two crashes. I haven't found a way to reproduce it, but I do have firefox open and last time it crashed when I was just typing some text in firefox. Before the last time it has crashed few times when I've switched between virtual desktops.
What always happens is that CPU level goes to 100% before the crash (I've gkrellm running) and then I end up with a black screen with a blinking cursor. Last time I was able to login with ssh from another machine and start KDM remotely, but I've had crashes that kills sshd too. My daemon.log said last time: ----8<---- Jun 12 16:33:57 localhost kdm[5204]: X server for display :0 terminated unexpectedly Jun 12 16:34:00 localhost kdm[5204]: Unknown session exit code 0 (sig 11) from manager process Jun 12 16:34:04 localhost udevd-event[12190]: wait_for_sysfs: waiting for '/sys/class/vc/vcs7/·' failed Jun 12 16:34:04 localhost udevd-event[12191]: wait_for_sysfs: waiting for '/sys/class/vc/vcsa7/·' failed Jun 12 16:36:00 localhost udevd-event[12307]: wait_for_sysfs: waiting for '/sys/class/vc/vcs7/·' failed Jun 12 16:36:00 localhost udevd-event[12308]: wait_for_sysfs: waiting for '/sys/class/vc/vcsa7/·' failed ----8<---- I've also had the same NetworkManager messages there, but I removed it earlier when I thought it was the reason for my crashes.

Make sure the message bus daemon is running! ----8<---- (I removed the bluetooth stuff after that too, but it wasn't the reason for my crashes either.) I use also KArm, which is using 100% CPU time for many seconds when changing tasks now in Feisty, but I guess that hasn't anything to do with this issue. One other thing that uses all CPU resources is the logout fade, but these are probably just KDE issues. These crashes are bad, and since this bug was the closest I could find there must be some configuration or driver issue. My X configuration differs from many others since I have two monitors using xinerama, which might have something to do here. (No 3D accelaration of any kind because of that...)
