this is a duplicate of bug 15005 and we don't want to have two bug reports for the same issue.
so please left this bug closed and let's look at the issue in bug report 15005. :)

please re-open it if you don't think it's a duplicate of bug 15005.

I tried the patch, but it does not compile.

kernel/time/clockevents.c: In function 'clockevents_notify':
kernel/time/clockevents.c:262: error: implicit declaration of function 'tick_is_broadcast_device'
make[2]: *** [kernel/time/clockevents.o] Error 1
Comment 8 Zhang Rui 2010-01-28 01:09:06 UTC
hmm, what's the kernel version you're using?
why not get the latest kernel source on Linus' git tree and see if the problem has been fixed?
