Bisected it: #################################################################### 7503bfbae89eba07b46441a5d1594647f6b8ab7d is first bad commit commit 7503bfbae89eba07b46441a5d1594647f6b8ab7d Author: Mike Travis Date: Sun Jan 4 05:18:09 2009 -0800 cpumask: use work_on_cpu in acpi-cpufreq.c for drv_read and drv_write Impact: use new cpumask API to reduce stack usage Replace the saving of current->cpus_allowed and set_cpus_allowed_ptr() with a work_on_cpu function for drv_read() and drv_write(). Basically converts do_drv_{read,write} into "work_on_cpu" functions that are now called by drv_read and drv_write.

So I guess theres something wrong here. Please tell me which information you need to fix the problem, I will help as I can. > > Ingo > cu Dieter -- 3rd Law of Computing: Anything that can go wr fortune: Segmentation violation -- Core dumped
