Kernel Dmesg Logs for single display LFP boot.
The system configuration is as follows
Laptop - Hp pro-book 440 g3
SKU - SKL GT2
OS - Failed in same way for Elementary OS, Ubuntu 17.04
Native Resolution - 1366x768
System boots without flickers if we put nomodset, but not otherwise. Already
tried almost latest drm-intel-next. Dmesg attached(for Ubuntu single display
boot). Some experiments done which do not have any impact - disable rc6, FBC,
DC states
Connecting an HDMI in dual display config, has HDMI working but thats on 10x7
config and not in its native 14x9. Local eDP still continues to flicker like
crazy. Don't see any under run error logs.
Any patches to try just let me know and I can get the testing done. Right now
short on time and resources to debug myself and any help/pointers will be very
much appreciated. Thanks.</pre>
