Kubuntu 16.10: Radeon error atombios stuck in loop
From FVue
Problem
During boot of Kubuntu-16.10 these error message appear on screen:
[drm:atom_op_jump [radeon]] *ERROR* atombios stuck in loop for more than 5secs aborting [drm:atom_execute_table_locked [radeon]] *ERROR* atombios stuck executing 72E0 (len 237, WS 0, PS 4) @ 0x72EE [drm:atom_execute_table_locked [radeon]] *ERROR* atombios stuck executing 6C78 (len 74, WS 0, PS 8) @ 0x6CAD
Environment
- Lenovo ThinkPad S540
- Graphics Card AMD Radeon HD 8670M
- Kubuntu 16.10
$ lspci | grep -E 'VGA|Display' 00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 09) 06:00.0 Display controller: Advanced Micro Devices, Inc. [AMD/ATI] Sun XT [Radeon HD 8670A/8670M/8690M / R5 M330]
Solution
Remove the `radeon' driver, so the only driver loaded is the `amdgpu' driver. See https://wiki.archlinux.org/index.php/AMDGPU#Disable_radeon_driver :
$ cat /etc/modprobe.d/radeon.conf # https://wiki.archlinux.org/index.php/AMDGPU -- FVu, Feb 19, 2017 blacklist radeon
Now only this graphics driver is present in my X configuration:
$ cat /usr/share/X11/xorg.conf.d/10-amdgpu.conf Section "OutputClass" Identifier "AMDgpu" MatchDriver "amdgpu" Driver "amdgpu" EndSection

Tried to install the AMDGPU-PRO driver by following instructions from http://support.amd.com/en-us/kb-articles/Pages/AMDGPU-PRO-Install.aspx. But after reboot and selecting GRUB entry the screen remained black. Fortunately I was able to do:
amdgpu-pro-uninstall
