weird lg e467f brick or "SensorService : sensor poll failed."

Hi there !
Does anyone with a LG Optimus can check this stuff ?

Mine bricks (by natural means, i guess). After boot, he starts saying "Google Play stopped". Soon, "Youtube stopped", etc, etc.

When i do a "adb shell logcat", there is a bunch of this message :

Code:

---

                                      :
E/SensorService(  595): sensor poll failed. count is 0
E/SensorService(  595): sensor poll failed. count is 0
E/SensorService(  595): sensor poll failed. count is 0
E/SensorService(  595): sensor poll failed. count is 0
E/SensorService(  595): sensor poll failed. count is 0
E/SensorService(  595): sensor poll failed. count is 0
E/SensorService(  595): sensor poll failed. count is 0
E/SensorService(  595): sensor poll failed. count is 0
E/SensorService(  595): sensor poll failed. count is 0
E/SensorService(  595): sensor poll failed. count is 0                                  :

And "adb shell top" returns :

The phone becomes hot and, later, very slow.

So, i rooted it and, just to investigate, killed the kuInotify process.
After that, it cools and stays responding gestures.

I haven't another LG device here, to see if these outputs are the expected ones.

Questions are :
(1) Can someone check a LG logcat output and see if it is flooded with "SensorService" messages ?
(2) What is kuInotify ?

Very thanks !!!!!!
