BETA5 freezes (SMP + mpsafenet)

Hello,

I'm experiencing hard system freezes on a BETA5 system (which was
previously running BETA2). I am not able to get any debug information
from that, the system doesn't react to anything, even numlock & co don't
work.

I've done some testing. Turning WITNESS and INVARIANTS on didn't help,
but after turning mpsafenet off the system has already 26 hours of
uptime. The freezes happened after a few hours and they weren't related
to some particular system activity (or at least, one I could notice).

The system is running pf and netgraph bridging. System complains about
some interrupt storms on fxp1. Here comes the dmesg (it's with mpsafenet
off, but it isn't much different):

Is there anything I can do to provide more information?
