Your system is missing the radeon firmware which is required for the chip to operate properly. Please install the firmware. Where is radeon firmware? How can I install radeon firmware? In my option, radeon firmware is the option rom on graphic card, my system must contain it, my system can display normally during bios, grub and kernel early phase. If I add nomodeset boot option, the system is ok using efifb driver. Anyway, the system is normal in kernel 3.13, but it is bad since kernel 3.14-rc1. It's better that radeon drm driver could handle this exception. It's included in the linux-firmware tree. The firmware is required for proper option of the gpu beyond basic bios services (high bandwidth displays, acceleration, etc.). After I copy radeon firmware to /lib/firmware, my system can boot up using latest upstream kernel. It's strange that ubuntu 14.04 server doesn't contain radeon firmware defaultly after installation. |
