I'm also suddenly having a panics - every 5 minutes actually, since my
latest cvsup a few hours ago. They seem to be related to some ufs
and ffs calls..
I'm not able to read my core dumps for some reason (gdb says "kernel
symbol 'cpuhead' not found.") and I don't have the time to scratch a
backtrace down by hand just now.
The panicstring is: "bremfree: bp 0xc77e8670 not locked"
Sincerely,
Rasmus Skaasrup
