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,
tglx
