Zeeb --- (In reply to Robin Haberkorn from comment #14) Hi Robin, thanks a lot for going the full way of finding a reproducer. That should also make it easier here to go and see about it if it works equ= ally well in my setup. I've got this on the radar but there's only so much fish I can fry a days t= oo ;-) If you find patching your iwlwifi with extra NULL pointer checks help it'll be good. It might still be that it'll just make it harder to his a r= ace against something else but in the end everything will help at the moment. What would be interesting to know if you can panic this reliably and have t= he opportunity to further debug is what happens on the other CPUs at that time= so we could identify the case we are racing against. --=20 You are receiving this mail because: You are on the CC list for the bug.=
