Kernel panic with Xpmac using recent kernel 2.2.0-pre7

[Marc Dejardin]

Kernel panic with Xpmac using recent kernel 2.2.0-pre7 (or all > 2.1.24).

Recently I have tryed to update my kernel to recent ones (I was using 2.1.24 
witout any problem) and I encounter problem when I use Xwindow. In general I
have a kernel panic after some seconds or minutes when I launch an application
which uses X11 (xearth, gv, netscape, ...)
The problem does not occur always at the same time. It seems linked to the fact
that recent kernels for linuxppc are optimised for XFree86 and the
compatibility with the old Xpmac is not perfect.


Linux version 2.2.0-pre7 (dejard1 at xxxxxx.xxxxxx.xxx.fr) (gcc version
egcs-2.91.57 19980901 (egcs-1.1 release)) #1 Fri Jan 15 15:50:46 CET 1999
