Hi,

my very new kernel [1] makes my console freeze but I can still pings
the box and even login with ssh.  When I enter the debugger, the
console "de-freezes" while in but as soon as I type "cont", it freezes
again.

I have noticed this problem two or three times for the last few days.
My kernel configuration is attached.

I would like to have some pointers to be able to provide some useful
debugging informations.  Note that it would be better if it can be done
through ssh since I have no console cable, but if it's needed I will
hand-write DDB output.

Thanks.
Best regards,

[1] FreeBSD 6.0-CURRENT FreeBSD 6.0-CURRENT #57: Tue Feb  8 00:08:50 CET 2005
