It is what it is, everyday I try to argue in favour of the project, I still use it for myself everywhere but increasingly things happen that just don't on other volunteer projects... it's rather difficult to argue the case when they can install Ubuntu or whatever nonsense distro is the current favourite and it just works.  Just a bit more accurate info would solve it, if it doesn't do X reliably, or Y has changed, note it.

Yeah my gripe isn't with having no responses, the handful of people that 
have responded have been helpful but ultimately no responses from anyone 
involved.  Just a one liner saying "we changed the timecounter stuff in 
9, look at sysctl tree X" would have been more than sufficient, this 
sort of thing should really be mentioned in the relnotes though...

For the record though, setting kern.eventtimer.periodic to 1 fixes the 
problem on all affected machines (returns my virtualbox guest to 
normality, reduces the drift on physical machines to 8.2 figures).

FWIW, I can't even see any notes relating to this in UPDATING either.
