I just got a panic. As I have never had one before, I don't know what to

me some advice, I could try to help debug it; however, as I'm not a
coder (not a real one anyway), I don't know how much help I would be.
It's a 5.0-CURRENT system, just installed and built last week. It
paniced right after doing a source update (not a build, just cvsup).
The panic error is as follows:
panic: mtx_lock() of spin mutex vnode interlock @
/usr/src/sys/kern/vfs_subr.c:3187
Take a look at http://www.lemis.com/texts/panic.txt or
http://www.lemis.com/texts/panic.pdf and tell me if that helps. This
will be going into the new edition of The Complete FreeBSD in a few
days time, so I'm interested in getting something which is helpful.
Hi Greg,
I've been looking at doing the same thing, learn how to capture a crash dump,
and analyze it etc. I'm a definite newbie at that so I thought it would be a
good test for the article. It's pretty readable, but I had a problem with
enabling the crash dump as noted:
To enable dumping, put something like this in /boot/loader.conf:
dumpdev=/dev/ad0s1b
that gives an error that is similiar to:
WARNING: syntax error on file /boot/loader.conf
dumpdev=/dev/ad0s1b
^
the same syntax in /etc/rc.conf worked fine, however.
This was on 4.8 RC2, but the syntax error appeared on a recent -current too.
Thanks,
Tim
