There was a bug some time ago, which was fixed for TIMER3, see commit:
http://git.xenomai.org/?p=ipipe-gch.git;a=commit;h=ebf2fac4298e25509ba47942b9fad408dcefce1e

But I think your problem has more to do with the following commit, could
you try reverting it?
http://git.xenomai.org/?p=ipipe-gch.git;a=commitdiff;h=6ab29d9c7a4b119f45ef4d93780e894fe1c0c6c6;hp=cd9c5e016092258d4450e137be2d0844d0fe8b38

The same issue was reported on ixp4xx.
