<pre>I just bought a Dell Venue 8 Pro - an 8" tablet based on the Bay Trail platform
- to try and get Fedora running on it.
After hacking things up to produce a bootable 32-bit UEFI image, next come the
kernel bugs :)
If I boot an image with a 3.11 or 3.12 kernel and default boot arguments, the
display becomes badly garbled as soon as modesetting kicks in; it looks like it
selects the wrong mode. If I boot an image with kernel 3.13.0-0.rc1.git0.1 ,
the screen just goes blank (backlight still working) when modesetting kicks in.
For now I have no further details, as I don't have a USB hub to hand so there's
no way I can get any out. I'm going to pick up a USB hub tomorrow so I can have
both the boot media and a keyboard connected, and I should be able to get some
more useful info at that point.</pre>
