hi, we meet another desktop crash issue.
we use R38.2.1 version.
this issue is different with below issue. we already set gpu with performance mode to disable devfreq to work.
devkit的频率问题，我们另开topic来讨论，这个topic我们继续跟踪桌面卡死的问题。

when desktop crash issue happen, xorg and gnome-shell take 100% of a cpu core.
when desktop crash happen, this thread enter D status.
if set /sys/class/devfreq/8188050000.vic/governor as performance, still can reproduce this issue.
