Context switching disabled while dumping?

[SWTRINITY@xxxxxxx]

I am using lkcd with a 2.2.16 kernel and
I seem to be seeing a problem where context switching
is occurring while the dump is ongoing. This causes
processes to switch in and change the state. I saw this
behavior with the automounter switching in 
and causing another kernel panic. Does
context switching need to be disabled while 
the dump is ongoing and if so, how is this accomplished.

                   Thanks
                        Les.
