42m TRH on tower

As a hack earlier today I tried to power cycle the 42m TRH on tower, in the (small) hope that it might resolve the temperatures that are too high there.

But "eio 8 0" had no effect, data was still coming in on the port.   "eio 8" always reported 0 even after an "eio 8 1".

So it seems that the emerald was not responding to commands at address 0x200, even though the serial ports, at 0x100 to 0x147 were working.

Copied over a new emerald.ko driver module, which has a fix for the EEPROM accesses in the hope that may help the emerald respond.  The old one is saved at /lib/modules/3.16.0-titan2/nidas/emerald_save.ko.

After ddn, a "/etc/init.d/emerald start", failed because the emerald would not respond at 0x200.  So just did a remote software reboot.  All came back.

From kern.log:

Oct 21 18:04:12 localhost kernel: emerald: NOTICE: version: v1.2-435
Oct 21 18:04:12 localhost kernel: emerald: INFO: /dev/emerald0 at ioport 0x200 is an EMM-8P
Oct 21 18:04:12 localhost kernel: emerald: INFO: /dev/emerald0: port 0=RS232,1=RS232,2=RS232,3=RS232,4=RS232,5=RS232,6=RS232,7=RS232

So it is running the new v1.2-435 of emerald.ko.  Controlling power with eio then worked.

The power cycle of 42m didn't help though:
