Only 6 for "... Successfully initialized GPU X".
Thats actually a good thing from my perspective, it points to the init phase not working properly, not the core mining process.
I have a build available very shortly. Are you available for a quick test? Id love to see if this solves your issue before we push it as an official release.
Anyone else available right now that has had the some-subset-of-my-gpus-dont-work issue and are willing to test a patch, reach out to me over PM or find me on Discord (Zcoin/fpga/mineority/lux/cryptobridge are some servers Im available on).
