So the actual problem is two-fold: - X11 livelocks, where I can login via ssh and kill . - When I use gdb -p, it prints out the same message reported here: <http://osdir.com/ml/gdb.bugs.discuss/2005-04/msg00043.html>. The only thing is that if I press `y' on the first go-around, the machine hardlocks on the first try with hitting `y'. If I hit `n' so gdb coredumps, I can either go on my merry way, or go back to the confirmation dialog. If I hit it again, it doesn't hardlock. It does hardlock though, and for whatever reason my PC speaker beeps, and I have to warm boot it. I haven't been able to get a kernel dump though, so something else mysteriously is going on that I can't track. So, just to simplify: first_try := True while gdb is running: if prompt_for_coredump() and first_try is True: panic() first_try := False Thanks, -Garrett
