20140516 14:49 Window of LXDE popped up saying had kernel failure.

Failure occurred yet again as handful of times prior versions in past couple years related to USB

Last time was USB TV adaptor was inserted after had been removed.

This time umounted wip 8gb ArchLinux USB created on T5730 with umount command in system since early hours of this morning,
then inserted 2gb USB that has boot/install image of ArchLinux used on T5730 to create the WIP ArchLinux on 8GB flash
at which point kernel failure occurred.

unmount was done via console which already has console logging enabled:
