 oh... one thing that may be keely relevant: there's no RTC on the
EOMA68-A20 board.  as in: the normal place where the kernel would get
"time" from would be a battery-backed AXP209.  in this case, however,
it's powered from "cold".

 so it's actually quite likely to be a major bug that has simply had
insufficient coverage to expose it.
