How can i force a crash dump on a running system f. e. with "dbx"? Digital Unix 3.2d-1, halt and srm-commands couldn't be used for some reasons.

This works for me:
# dbx -k /vmunix
(dbx) assign kmembuckets[0].kb_next = 1
This corrupts a kernel memory bucket pointer. The next piece of kernel
code that tries to allocate memory from the bucket will try to access
virtual address 1, take a kernel memory fault, and panic. This should
happen virtually instantaneously.
Happy crashing,
Martin

Another one
a pidtab=0
I am sure there are lots of way of crashing kernel :-)

dbx -k /vmunix
(dbx) assign hz=0
Someone else gave me this. It causes a divide by zero. Real fast and
it doesn't mess up any addresses.
