[comp.unix.ultrix] Core dumps on DecStation 3100?

tim@appenzell.cs.wisc.edu (Tim Theisen) (11/30/89)

I am debugging an unsupported portion of the kernel and I am having trouble
getting a core dump.  The problem is that the machine hangs such that the
only way that I can get it to respond is to push the reset button.  At this
point I hold down a key so that the machine exits from its self test before
testing memory. Going to the doadump routine at this point does not produce
a core dump.

It would be very helpful to get a core dump from this hang.  However, I suspect
that it might be impossible.  (I have been able to get core dumps from panics.)

Any advice is appreciated.  Thanks in advance,  ...Tim
