Hello guys,
Saw the error you were describing and it seems that I get an identical behavior. It seems that my Hex16A2 miner slowly degrades at a point where it doesn't hash at all. Did try to restart the process only but didn't manage to do anything. Today I did shutdown all miners (3 Hex16A + 1 Hex16A2) after I got an email from btc-guild that my miners where off. Turned them back on and everything started ok but got many duplicate errors (only from my Hex16A2 miner) and also noticed that the speed is degrading again. BTW I'm using cgminer 3.8.5 on a linux mint laptop. Should I manually apply this:
Guy's,
I found a bug for hex16A2 boards loosing woork of chip 0 - 87f0213112a3c69e2c55160b9c674b9de2cde996_u_1d.patch
while waiting for fix you can change
driver-hexminerc.c line 363
if (libhexc_cachenonce(&array_nonce_cache[0], nonce) && libhexc_cachenonce(&array_nonce_cache[lastchippos], nonce)) {
to if ( libhexc_cachenonce(&array_nonce_cache[lastchippos], nonce)) {
This will bring back some dupes but will increase the performance with 1/16
Best,
Twisted
