>Description:
Within seven days i had two kernel page fault with immediate machine reboot.
I have a x86 HP workstation 4200 with SATA raid (1) controller.
After the first panic, I rebuilded everything, system binaries and kernel (without errors).
The kgdb report the following:
[root@dbs /var/crash]# kgdb /usr/obj/usr/src/sys/BEPPEBIS/kernel.debug /var/crash/vmcore.1
[GDB will not be able to debug user-mode threads: /usr/lib/libthread_db.so: Undefined symbol "ps_pglobal_lookup"]

Any idea. The desktop machine was very idle. I suppose no load problems, no extra charges in network connections.
