Hi Claymore,
Thanks for the great miner!
I have a number of rigs with 380x cards, one with a mix of 380 and 380x and a "new" one with one ASUS STRIX-RX480-O8G-GAMING and one ASUS DUAL-RX480-O4G. They all run Ubuntu 14.04.4, except for the new one that runs Ubuntu 16.04.1
The rigs with the 380x and the 380/380x cards run smoothly since day 1, but the "new" one has the following problems:
1. The two cards cannot work together. ethdcrminer64 just crashes at random intervals. The situation is even worse under Windows 10: the system just reboots... I don't even get a decent BSOD. My solution is to run (under Ubuntu) two instances of the miner, one for very card.
2. The hashing speed goes up and down. The RX480 with 4GB hashes between 15MH/s and 21.5MH/s and the RX480 with 8GB hashes between 17MH/s and 25MH/s
3. I get LOTS of system errors. By lots, I mean 100GB of kernel and syslog messages in a couple of hours. I've disabled syslog and set -dbg -1, but still... I'm pasting a few dmesg messages below

Any help on any of the problems will be greatly appreciated.
