Patch doesn't work on AMD Piledriver

Never mind, used a backup from before trying KVM and applied the patches there: Crashes gone. Except a crash on shutdown, any idea what's causing this (it's not there without KVM) ?

For reference: Q239887 is applied (and as said: The crash doesn't happen without KVM). This is how the screen looks like:

(The cursor is blinking).
