Thanks for the info

A risky one !! Most if the hardware testing had been done with 11.4 I'm testing 11.6 as we speak

if I think it's stable enough I'll add it as an option via the package manager.
Yeah, I know drivers are always an issue. If it was just a normal update I would not ask for it, but I think not having to flash your cards is worth it. This was actually the only thing that was missing in Linux for mining. Now you can use AMDOverdriveCtrl without stupid limits.
Well, one thing is missing in Linux and its being able to read the current and the temperature of the VCC's. RadeonVolt does it, but only for some 5850's. I wish there was a way to do it for 5870's.
