panic after xdm is started

[Johannes Hofmann]

Hi,

with recent kernel (v2.7.3.840.gf5f1b-DEVELOPMENT) I get a panic on my
UP laptop when I start xdm. Xorg without xdm works ok.
It seems that after xdm has been started a subsequent
kprintf() causes the panic. I've seen different kprintf()'s causing
this. The panic message is:
panic: Attempt to acquire token 0xc03dc800 not already held in hard
code section
A dump is on leaf.

Cheers,
Johannes

PS: With this new kernel the system (or is it X11?) feels a lot
    snappier :-)
