Hi

Since some days my system is very unstable. I get many crashes with kernel 
panics.

First one app is killed because of a segfault, than it doesn't take a long 
time and the computer is down. What is the problem, is it a memory error ?

thanks
have fun
Felix


P.S. Here is one of this crashes:

hal@hal:~$ ksymoops -m /boot/System.map error.txt

This is slower than the current DRI can do ;-)

dual Athlon MP 1900+ (but all XFree and Mesa stuff is single threaded 
currently):

Mesa/demos> ./gears
r200CreateScreen
6465 frames in  5.000 seconds = 1293.000 FPS
11955 frames in  5.000 seconds = 2391.000 FPS
11954 frames in  5.000 seconds = 2390.800 FPS
11955 frames in  5.000 seconds = 2391.000 FPS
11954 frames in  5.000 seconds = 2390.800 FPS

I wonder why nobody point to the place were "the real development" is?

dri.sourceforge.net
or the new test site (under construktion)
http://lfm.sourceforge.net/dritest/

Xv is supported with the current trunk, too.
If you need the video capabilities take a look at the GATOS page.
http://gatos.sourceforge.net/

Cheers,
