i915_error_state

Whenever I started playing video using mplayer, my srceen became frozen, took
long time switching to tty using ctl+alt+f1. there are several lines in the
output of `dmesg` like:

[  112.471206] hda-intel: IRQ timing workaround is activated for card #0.
Suggest a bigger bdl_pos_adj.

I've google a lot but none of them solves my problem.

uploaded `/sys/kernel/debug/dri/0/i915_error_state`, hope it helps.

I'm ready to provide any log necessary.
