I've been away for four days, arrived home last evening, had the Iyonix
on for several hours, fetching email etc. without any difficulty. This
morning I turned the system, it started up normally, but after about an
hour the ethernet connection dropped.

Okay - and the PSU is still reading 5.07V.

I've powered the switch down and back up - this makes no difference to
the status of the Iyonix link. All the other ports came back up as
normal. I have tried connecting the Iyo to an alternative port, with a
different cable - this makes no difference either. I have tried
connecting another device to the port usually used by the Iyo, and the
other device is perfectly happy using that port.
All the indications are that, although the Iyo believes that the status
of the EtherK port is good, it is that, in fact, Etherk which is
failing.

Can this be done on the running system, or is it only via the Configure
eklink command, to take effect on the next start up?
As before, Rmreinit Etherk brings the link back up successfully:
: *rmreinit etherk
: *eklog
: EtherK has logged 3 messages for unit 0.
: 11:41:02 14-Aug-2006: Initialising device
: 11:41:02 14-Aug-2006: Device initialised successfully

Has anyone any clues as to what is going on here?
