Same here with random freezes. Tried intel_pstate=disabled which works.
However, cutting the max GPU frequency to about 50% also works for me. Video
seems smoother compared to pstate=disabled. YMMV
Running 64 bit Mint 17.2/Cinnamon on ASUS T100-CHI linux-4.2.5 w/Ubuntu base
and T100 specific patches. (Intel Atom Z3775, ValleyView Gen7)
Also seeing freezes on Dell Inspiron Laptop (Intel N3540) with various Ubuntu
kernels from 4.3-rc7 back to 3.18.21, though usually much less than once a day.
CHI without workarounds usually freezes within minutes to several hours.
Software rendering improves run time/reduces freeze rate. However, with GPU
capped, it runs as long as I let it - usually a few days.
