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 ?
