Problems with timers with linux-next on snowball

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1

Hi,

while trying the linux-next at the point it boots (commit be9b7335e70696bee731c152429b1737e42fe163, after v3.2-rc4), I noticed the timers were not working properly with CONFIG_NO_HZ.

It is easy to reproduce with 'time sleep 1' where the timer expires 1, 2 or 3 seconds later.

It seems that does not happen with linux-linaro-3.1 but I was able to reproduce the problem on a vanilla kernel 3.1.5.

Is it a known problem ?

Thanks -- Daniel
