I can see it, this is no where going forum, but my problem is wired. PhoenixMiner 5.6b everything works, on PhoenixMiner 5.7b one GPU doesn't work, I'm noob, so I don't know much about setting up the files, that's why I put the log up to see if someone from here help brother out.
I haven't been around much, mostly because things had been working well for me until two days ago with Radeon Software 21.9.1 where PhoenixMiner broke again. I'm not on the Linux side, so can't tell you the specifics, but the big problem comes from driver versions that clash with PhoenixMiner. Things work, you install new video drivers, and PM stops working. Go back to previous video drivers, and it works again. AMD has been updating and changing the drivers to add features and improve performance of the Radeon 6000 series(I have a 6800 so also know the Big Navi pains of PhoenixMiner breaking). As long as you keep your drivers to something supported by the miner, you are fine. You can add the manual -clkernel 0 to get around THAT problem, but it is less than ideal.
Yes, there are very few posts by anyone from PhoenixMiner, and it is annoying, to the point where I and others are tempted to change for a miner that actually has SOME presence to address questions/problems when they come up. The real key is that many are busy at this time of the year, and we don't have the time to tinker with a new miner to get it working, at least as well as PM does when it works.
