Hi Guys,

Had a page fault when doing a startx to run Mate desktop as I usually do
.... first time it happened.
dmesg error is:

iicbus6: <Philips I2C bus> on iicbb3 addr 0xff
iicbus8: <Philips I2C bus> on iicbb4 addr 0xff
iicbus10: <Philips I2C bus> on iicbb5 addr 0xff

Any ideas why this happened? After the re-boot everything came up fine ..
