--- Comment #92 from Maxim Sheviakov mrader3940@gmail.com --- So, got my PSU yesterday. Compiled 4.3.3-zen with -Ofast + those patches, quirk removed and firmware added to initrd. Modesetting works, I'm able to see Plymouth finishing its animation. However, at X start stage I get a complete hang, but monitor's active. It's likely a PM error, as else there would be a hang at modesetting stage. It's similar to an issue I had when compiled the kernel with quirk containing my card's normal MEM and CORE clock values - hang due to PM error.
Should I do something else? And is there a way to make the card work at its normal frequencies?
