dmesg output with drm.debug=14

Attached is output from "dmesg" and "lshw".


-- system architecture: 64-bit

-- kernel: 4.9.0-994

-- Linux distribution: Ubuntu Gnome 16.04

-- Machine or mobo model: Tesco Windows Connect

-- Display connector: ???

I'm using a  10.1-inch Cherry Trail tablet. The kernel is drm-intel-nightly branch (drm.debug=14) and is 64-bit booting from a 32-bit uefi with grub2 (dunno if that's relevant or not).

When I boot, text scrolls down the screen and after a few seconds the text gets wiped off leaving a black screen.  This issue does not correct itself, but I can type commands into a tty without remote access (just can't see the commands I type in).

I'm not sure if this is the right channel to report this, and I appreciate there are other details I may need to provide.

Thanks.

p.s 
As noted in similar bug reports, there are other problems with the device as well. I don't have any audio (not sure if that's because I've not got the right driver), and there's problems with hardware buttons and sleep mode.

shadoe_da_deaddonkey@yahoo.com - I'm sorry about this delay for getting back to you. Have you seen this failure lately? Preferable with the kernel compiled from drm-tip.

Timeout - marking resolved+worksforme. Please reopen the bug with the latest information from the latest kernel (preferable from drm-tip) as guided on https://01.org/linuxgraphics/documentation/how-report-bugs
