Current is in a very desolated state

[Martin Blapp]

Hi all,

Even with the disabled preemtion CURRENT is in a very desolated
state at the moment - and this one week before freeze.

While I was able to run a server with 5.2.1 about 1 month without panicing,
this is no longer true with recent current.

The panics I get are in the timer codepath or sometimes in the vfs layer.
It's very easy to kill the machine with high load (rm -rfd /usr/src
while running a make world -j 10) kills the server.

I also get this panic after 20 - 30 minutes load

This is an SMP box with two XEON's, running a SMP kernel with SCHEDBSD.
