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.
This didn't help T.42m though:
