Hi,
using Ian Campbell's PSCI patches for U-Boot (ported to master, see
[1]), I managed to enable KVM on the Jetson TK1 board. Unfortunately,
I'm getting a crash on the host when starting QEMU:

Host kernel is from Linus tree. I can try a different one if there are
pending fixes somewhere.
Any ideas? Anything I should look at in particular?
