Comment:

 OFW's main strategy for resetting the system is to call into the EC and
 let the EC do it.  If, after 3 seconds, the CPU is still running, OFW
 falls back to resetting the Via chipset directly using the 0xcf9 I/O port.
 That fallback strategy is not ideal, as it does not necessarily do the
 right thing with external I/O devices, but it is the best that OFW can do.

 In any case, the primary responsibility for the reset lies with the EC, so
 if it is not happening correctly, either the EC is at fault or OFW has
 lost communication with the EC.

 The incidence of this problem is low (only a few reports over a long
 period of time), it primarily affects developers instead of end users (who
 have little use for the ok prompt and "bye"), and there is a trivial and
 obvious workaround (power button), so there is little value in spending a
 lot of time trying to reproduce and fix it.  Hence I'm closing this
 ticket.
