I'm having 2 issues with this kernel:
1) When I connect an external USB keyboard, my TF hangs and I need to long press the power button to reboot it
2) HDMI switching between crop and scale mode is broken, TF is always in scale mode
I reverted back to stock kernel and don't have these issues anymore. Tried test 13 and 14 kernels, both having the above issues.
It would be great to have a kernel where only the reboot issue has been fixed, for those who don't need the other features like overclocking.
Anyway, I think you're doing a great job with your test kernels Guevor!
