kernel.log
On my ASUS Transformer Book T100HA, the built in DSI display fails to display
any image right after KMS takes over from efifb. The backlight remains on.
Please see attached for kernel log (drm.debug=0xe).
I am unable to obtain a VBIOS dump. Kernel says:
0:02.0: Invalid PCI ROM header signature: expecting 0xaa55, got 0xe725
Steps to reproduce the issue:
1) Just boot the device.
How often does the steps listed above trigger the issue?
Always.
The following information about your system:
-- system architecture: x86-64
-- kernel version: 4.6.0-994-generic (drm-intel-nightly from 2016-04-02)
-- Linux distribution: Ubuntu 15.10
-- Machine or mother board model: ASUS Transformer Book T100HA
-- Display connector: DSI</pre>
