It's worth double checking. I've forgotten to update my ucode a number of times and run into similar problems. Christian was using out of date ucode and when he fixed it his UEFI system started working fine. We can take a look at register dumps. grab radeonreg: http://cgit.freedesktop.org/~airlied/radeontool/ and dump the regs when booted with legacy vbios vs. UEFI and attach the outputs. boot with legacy bios (as root): radeonreg regs all > legacy.regs boot with UEFI (as root): radeonreg regs all > uefi.regs -- You are receiving this mail because: You are the assignee for the bug.
