At this chance... Reminds me that this old issue still seems to be
unsolved in current kgdb:

I'm only looking at that spot in kgdb right now and /may/ oversee new
border conditions elsewhere. But my feeling is there are none.

Hi Jan,
This issue was fixed in a generic way in the patch set that is in the
-mm tree. Had you tried your test case in the current -mm tree?
The problem you mentioned was fixed by saving and restoring the preempt
count as a part of the fault handling from the kgdb core and not in the
arch specific portion.
Jason.
