  i did have keyboard drops last night.  fell asleep
with the computer on so i know it wasn't me doing it.
:)  today i applied bigger hammer in udev rules file.

  previous masking of sane items made no difference
to that issue and i still think they may be related
issues.

  i went back to the bios and tweaked it some more.
been busy today typing so no drops the past few
hours.

  watching things via udevadm monitor to see if
that gives more info if/when it happens again.  first
i did make sure of what it looked like during a
normal disconnect like when i unplug/plug it back in.
