I wanted to try 2.6.11-mm2 for the low latency/realtime lsm stuff and
I've run into a severe

When I try to start X, my machine reboots. The screen goes dark as
usual when setting the video mode, but then I get a beep and I'm
greeted with the BIOS boot messages. This happened 4/5 times i've
tried, and once the video mode was actually set (at least I saw the
usual X b/w pattern with some random framebuffer garbage), the machine
didn't reboot but after that nothing happened. My keyboard was still
responsive (ie NumLock LED would still go on/off), but i could neither
kill X with CTRL-ALT-BACKSPACE nor could i switch back to console, so
I ended up pressing reset.

After the crashes I booted with a rescue CD to examine the logs, but I
could not find any obvious errors.

Everything works nicely on 2.6.10 and earlier kernels. I'm in the
process of building to see if the crash occurs there.

Here is some info on my system:

I've got an Athlon 1000C on a VIA KT133 chipset and a Radeon 7200 (the
original Radeon with 32MB SDR RAM). I'm running Debian/sid.
