BETA5 regression - reboots -reproducible

The "good" news is the it happens every time. The bad one - nothing
logged and no idea what it happens.

My "old" kernel+world was a BETA4 just before the apparition of
debug.witness oids. The new one is:
 # uname -a
FreeBSD 5.3-BETA5 FreeBSD 5.3-BETA5 #6: Sat Sep 18 22:55:04 EEST 2004     itetcu at  i386
so the time frame is pretty small.

Kernel and world were build with NOCLEAN (I'm rebuilding now after
removing /usr/obj).

The problem:
Each time I try to play a video file with gmplayer or mplayer the system
reboots; no error logged.

This is a ULE, apic, agp kernel, with witness (but running with or without makes no difference) and invariants (see attached
conf file);
root(root)@it> /root [12:08:43] 0 # ll /etc/malloc.conf
lrwxr-xr-x  1 root  wheel  2 Sep  7 13:16 /etc/malloc.conf -> aj

An old BETA3 kernel that happens to lay around works.

The only thing I've noticed is that X takes a little longer to load (I
mean the initial X screen with the X mouse cursor stays a few seconds
before turning into KDE start-up screen).

Also running Xorg with or without dri makes no difference.

This is the console dri output when loading X:

*Anything* in order to fix this is very welcome.


Unregistered ;) FreeBSD "user"
5.3-BETA4 - try `sysctl debug.witness_watch=0`
and prepare to fly :-)
