Irina, a little more info on the symptoms. The user reports the
touchscreen works when restarting but fails when powering on.  He says
pretty much 100% of the time.  The log is the same...

Hi Brad,

Thanks for all the information you provided. I have already replied on the
Bugzilla thread with some patches that enable reset for the device.

Regards,
Irina
