   I don't know either. On my previous system (SuSE), I had available a
runlevel 3with a text console, and I could start X explicitly after I had
logged in. I haven't found a similar config in Kubuntu. I was wondering
about uninstalling kdm. Would that let me boot to a tty login prompt, so
that I could login, then start X? That might help determine if it's kdm
or X itself that's tripping up the kernel... ...or would that just break
the system?

   I checked that. The last 20 messages or so were exactly the same, both
when pooting the 686 kernel and crashing, and the 386 kernel successfully.

   I did try that as well. Very strange results! WHen I add the 'nosmp'
option and boot, the boot seems to take forever, I get a plethora of
spurious 'lost interrupt' messages, finally culminating with a message to
the effect of 'hda1 does not exist' and it drops me into a busybox shell.
My hard disk isn't mounted, but I was able to `cat /proc/cpuinfo' and
verify that it was indeed running in uniprocessor mode. Since I couldn't
mount the root pertition, I made no attempt to start X (startx isn't one
of busybox's builtin commands!)
