no problem.. I'll cvsup and make world as soon as 5.1 is released.
It's not a production server, so that's not a problem.
What is interesting is that with 4.7-Stable the faulty timer was
handled correctly (or correctly ignored).. so I'd suggest to fix
in software the hardware bug in 5.1-Release, or at least in -current.

I already had fixed it with sysctl, but I'll give a try to the
loader.conf solution as well.
Best regards.
