I tried drm-intel kernel commit:acd7e92bd669fbd86797cb763ded6b4980db7a62. This compile was complete. But system freeze was occurred on my BayTrail-I board. For 3.13.0-6-generic (Ubuntu 14.04 releases) kernel, this issue is not occurred. I found similar phenomenon report (<a href="http://comments.gmane.org/gmane.linux.kernel/1608974">http://comments.gmane.org/gmane.linux.kernel/1608974</a>). According to the report, this issue relates to drivers/cpufreq/intel_pstate.c. But I cannot find any difference of drivers/cpufreq/intel_pstate.c between drm-intel kernel and Ubuntu 14.04 released. Did you test this fixed kernel on your side with BayTrail-I system? I tried the drm-intel kernel on Ivy Bridge environment. The system could boot without the system freeze.
