That's the default setting I use for XFS debugging. I just put breakpoints on "panic" and "stop" (sometimes bust_spinlocks) and just let the kernel panic routine handle the segv which will trip a breakpoint. Then just walk back up the stack to the function that triggered the real SEGV and go from there. This is pretty much necessary for XFS debugging because just mounting a filesystem causes 8-10 SEGV signals to occur. You simply can't run xfsqa when that is occurring...
