No Linux kernel code should keep running for multiple seconds without giving
the scheduler a chance to schedule another thread. Hence the insertion of the
cond_resched() call.
It is very well possible that the fact that this code keeps the CPU for
itself so long is a bug by itself. However, I'm not familiar enough with the
ACPI code to figure out whether any alternative solutions exist that would be
better than the patch I posted.
