Barry Drake, thank you for performing the requested test. Given this is correlated to the desktop environment one uses, this would appear not to be a kernel issue, but something to do with userspace. I'll send to xorg (Ubuntu) for them to have a look.
** Description changed: Every third or fourth boot, the keyboard is not found although it is accessible by grub2 and by pressing <CTRL>+<ALT>+F2 and withing the terminal. Logout and login from the terminal followed by <CTRL>+<ALT>+F7 to reaccess X does not bring back the keyboard. My current workaround is to use suspend and then reactivate. This always - finds the keyboard after which all is normal. + finds the keyboard after which all is normal.
