	Hi
I have a problem with the dump driver. I was only testing it with
a "breakpoint" and "instruction fault", now i try the real life,
a good old "data page fault", but the problem is, it start the dump, 
but at the first try to write on the dump device if "sleep"
forever in "brw_kiovec". I'm pretty sure that it comes from
a spinlock deadlock. So I'm looking for someone who is able
to explain the "data page fault" function. 
For me it is the signal 15 in function handle_interruption() 
of traps.c. If it is the space 0 (kernel space), it call 
parisc_terminate(), that call dump() (my funtion). But in dump 
I use a buffer, and I use this buffer with "brw_kiovec". So I 
think that "brw_kiovec" do a page_fault somewhere, but because 
the previous page_fault fail, there is still a spinlock somewhere.
Can someone help on this issue ?

	Thanks.
