Have you verified your interrupt latency yet? See my earlier post if not.

Like Joel I'm using similar code w/o any issues.  I really think you need 
to verify that your interrupt latency is reasonable.  If you latency is 
longer than you expect then you will see exactly the behaviour you have 
described.

If you do find out it is unexpectedly long you can determine why but you do 
need to find out if it could be an issue first.  Running off after other 
issues without verifying may just cause you to burn a lot of time to no 
good purpose.  Unless of course you enjoy the frustration ;) but then I 
guess you wouldn't be asking for suggestions.
