The -oldconfig1 is the kernel that had no problems and the other shows the b44 
problem. So if High Resolution Timer Support is disabled everything works 
fine and if I enable it the problems do appear again.

I didn't test this on my 2.6.22-rc3 kernel yet, but I guess disabling High 
Resolution Timer Support will also solve the problem there.

The older kernels I tried also work perfectly fine and they didn't have the 
High Resolution Timer Support yet.
So, that's interesting, indeed.
Any idea what's going on, someone? Thomas?
Not off the top of my head.

Maximilian, does the kernel work otherwise (I mean aside of the b44
driver) ? 

Can you please keep CONFIG_HIGH_RES_TIMERS and CONFIG_NOHZ and try the
following combinations on the kernel command line:

1) highres=off nohz=off (should be the same as your working config)
2) highres=off
3) nohz=off

Michael, is anything in the b44 driver timer driven ?

Thanks,
