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 ?
