I am having exactly the same problem!  Did you ever get
it resolved?  If so, what must I do to get a stack trace.

Thanks,
George Uhl

---------------------------------------------------------

I have tried to debug a kernel by simulating a panic without success. I
have read the handbook and searched the mailinglist.  I even tried not to
strip the debug kernel at all. Still I get the above message and I do not
know how to go on.  The following are the commands that I used: 

now5# gdb -k
GNU gdb 4.18
Copyright 1998 Free Software Foundation, Inc.
......
This GDB was configured as "i386-unknown-freebsd".
(kgdb) symbol-file /kernel
Reading symbols from /kernel...done.
(kgdb) exec-file kernel.6
(kgdb) core-file vmcore.6
IdlePTD 3600384
kernel symbol `gd_curpcb' not found.
(kgdb) where
No stack.

Thanks for any help.
