Neither in X or normal terminal is there any response from the keyboard, except from ctrl-alt-del. Logging in is impossible. After CAD init displays a reboot message, but all other messages like unmounting the file system never appear. There is no disk activity and laptop does not shutdown. ssh is possible.

    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.

This commit has been reverted in mainline, so I think we can close this bug.

Please confirm that the current Linus' tree works for you.
