After I switched to Kernel 2.6.9 I realized a number of random freezes.
Yesterday I compiled the newer Kernel 2.6.10 and run glxgears. The system was
frozen after 15-20 s. I rebootet and run glxgears again (same result). After a
look in the Kernel's Changelog I realized a change of many DRM-Components
Kernel 126.96.36.199 works without any issues.
Steps to reproduce:
1. Compile Kernel 2.6.9 or 2.6.10
2. Run glxgears
The system freezes after a couple of seconds.
It might be helpful to know what graphic card you're using...
Sorry, I forgot this. I'm using the ATI Binary Drivers (flglrx) with my Radeon
9600 pro. The problem seems to be driver and Card-independent:
If you're using fglrx, you don't use any drm components of the kernel at all -
make sure you don't have them compiled in, since the radeon module cannot be
loaded at the same time as the fglrx drm module (you should certainly be able to
have it compiled as a module, it just shouldn't get loaded).
Glancing over that gentoo thread, I fail to see if/how that could be related.
Some of the people there are even using nvidia cards, and their code sure as
hell doesn't use drm kernel code (ati shares at least the drm design principles
afaik, but nvidia does not).
If indeed something in newer kernels causes problems with ati or nvidia drivers,
you'd need to complain to them.
