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.
This might sound harsh but here it is.
Sometimes users here can help you, sometimes not. Sometimes they want to help, sometimes they don't.
Phoenix people rarely post here anymore so you'll get very little or none from developers, they now depend on users
to do help and troubleshooting.
If you have no experience in mining and no ability to think on your own and do sequential logical troubleshooting and testing
and you are relying on others to kindly guide you through all your issues step by step you are probably in the wrong business.
Mining is NOT a plug and play project, it doesn't work that way. There are hundreds of combinations and setting that you will
have to do on your own. Sorry if the truth stings a bit.
I appreciate that post it is an investment and steep learning curve the step from Vega 2 to big navi has perplexed me till just now...
I have just solved my problem by jumping to a new distro based on Arch linux, before today i was a ubuntu man and have all progress today to thank for the info found in the post below copied here for any others who wish to mine a RX6000 series card in linux. Its a good place to start and this works i just done it though now need to go and unlock the kernel for tweaking the amdgpu pro but can report 60Mhs out of the box and the temp reported for the RX6800XT like this is low at 47C though she is pulling 220W for that so uvolt etc commencing in 321 kernel willing.....
