Fatal trap 12: page fault while in kernel mode

[Jonathan Bond-Caron]

Hi everyone, 

 

After cvsup to the latest freebsd 7 STABLE,  I did a make buildkernel,
installkernel. no issues so far

7.0-STABLE FreeBSD 7.0-STABLE #1: Sat Sep 13 14:08:08 EDT 2008     ..
:/usr/obj/usr/src/sys/WWW  i386

 

I can reboot with no crash using:

shutdown -r now

 

But when : 

 

bacula-fd

shutdown -r now

 

As it's shutting down, I always get a crash that looks like:

http://www.freebsd.org/cgi/query-pr.cgi?pr=126089

 

It's seems to be related to threads, rebuilding the kernel with makeoptions
DEBUG=-g

 

[root at martini] $ cd /usr/obj/usr/src/sys/WWW

[root at martini] $ kgdb kernel.debug /var/crash/vmcore.10

[GDB will not be able to debug user-mode threads: /usr/lib/libthread_db.so:
Undefined symbol "ps_pglobal_lookup"]

kgdb: kvm_read: invalid address (0x0)

Attempt to extract a component of a value that is not a structure pointer.

 

I am building the kernel wrong? I've never had to use kgdb before. 

 

 

This is a dell 1750 (poweredge). I'm 99% sure it's not hardware related
since putting the drive into other stable machines (other dell 1750's) makes
them crash as well using:

bacula-fd

shutdown -r now

 

Note: I also get the same crash when trying to install python from the ports
(crash at: configure: checking for pthreads..)

cd /usr/ports/lang/python24; make install
