Having priority 500 for unstable, testing, stable and oldstable really doesn't make sense to me... And Debian doesn't have (yet) a 4.4 kernel.
I tried a Debian release kernel and didn't get a lock-up under gdb / KDE, then tried my latest home-built kernel and didn't get a lock-up under gdb / KDE either.
Thanks for the suggestion - it appears to be a case of trying to change different variables and see if there are any consistent patterns.
