Hello!
I am running FreeBSD 6-STABLE (last update 14.5.06) on a Fujitsu Siemens
Amilo A notebook. This machine has internet access via kppp and a
Creative ModemBlaster V.92 serial modem.
Sometimes when surfing on the internet (most times with Opera 8.51
AFAIR) the system completly locks up and reboots. I found
http://www.at.freebsd.org/doc/en_US.ISO8859-1/books/developers-handbook/kerneldebug.html
and tried to analysis the crash dump in /var/crash but I am totally new
to these things.
"kgdb kernel.debug /var/crash/vmcore.2" on my system gives the
following
output:
[GDB will not be able to debug user-mode threads:
/usr/lib/libthread_db.so: Undefined symbol "ps_pglobal_lookup"]
GNU gdb 6.1.1 [FreeBSD]
(...)
Unread portion of the kernel message buffer:

Has anybody an idea what goes wrong on my system? What could I do in
order to find out what goes wrong?
Many thanks in advance,
Michael
