I tried to profile Genio and, on exit, I hit a KDL. Looks a lot like #15379.

Happens on 32 bit, too

We shouldn't be getting to profiling timer interrupts while the CPU is idle; that looks wrong. The thread should have been descheduled and the timer deactivated.

I haven't seen this before. Any particular settings you have which may affect things?

It's a vm (qemu-Kvm). I forgot to say I tried profiling another app (BeScreenCapture) and I don't get the KDL. Profiling Genio hits the KDL 100% of the time
