David,
I haven't done too much debugging with FreeBSD either. A few small
notes, however.
I don't think the gdb version shipped is ready to handle SMP kernels.
This is a deficiency, not sure someone is working on it, I believe not.
Having said this, it is probably impossible to find the kernel stack
pointer (as there are several of them anyways). Which in turn will make
it impossible to detect where exactly the kernel crashed. Unless you
have seen the machine crashing plus the report on the console, there
is not much you can hope for with this crash dump.
If this error is repeatable, you may have luck. Disable SMP in the
kernel and reboot, let the machine running until it crashes again.
Then, have another try.
FWIW, I do have a book on kernel crash dump analysis, it is for Solaris,
but I expect a great deal to be identical to general kernel debugging,
I haven't touched it in years. My debugging is somewhat different these
days.
Hope this helps.
Joerg
