[Bug 587039] [NEW] Ubuntu Lucid crashes at boot time with a kernel panic (fatal exception in interrupt)

[Launchpad Bug Tracker]

You have been subscribed to a public bug:

Since I've installed Kubuntu Lucid, I could start it two or three times.
Now, if I start Kubuntu, I either merely get a black screen or I get a
lot of error lines on my screen (I added "verbose" to the kernel
parameters myself so these messages appear). They say something like
this:

Then there is a non-blinking cursor and the system doesn't react anymore
and I have to reset it.

I have taken four photos for documentation:

If you want to know more about my hardware, please refer to
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/417683

All other operating systems on this PC (Windows XP, Ubuntu 8.04, Ubuntu
9.04, Fedora 12) work.

I also tried with the previous kernel that was installed originally, but
the result is the same.

If you need any further information, please don't hesitate to contact
me. I'd happy if I could use Ubuntu again.
