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 Christian was using out of date ucode and when he fixed it his UEFI system started working fine.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: <a href="http://cgit.freedesktop.org/~airlied/radeontool/">http://cgit.freedesktop.org/~airlied/radeontool/</a> 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</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
