Title:
radeon kernel driver fails to resume from suspend
Status in linux package in Ubuntu:
Confirmed
Bug description:
Hello everybody,
I'm using a laptop which is a Dell Latitude E6540 with hybrid
graphics:
00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core Processor
Integrated Graphics Controller (rev 06)
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI]
Mars XTX [Radeon HD 8790M] (rev ff)
The distribution is Ubuntu 18.04.2 LTS with HWE kernel
4.18.0-25-generic and HWE XServer packages. However, the problem
described below showed up with the standard kernel as well.
Kernel modules amdgpu, radeon, i915 are loaded.
From time to time, I suspend the laptop and switch from using the
laptop's primary display only to using one or more connected external
displays/projectors and back.
On resume, the window manager isn't started immediately. Instead, a
lot of error messages are displayed on the console:
radeon 0000:01:00.0: failed VCE resume (-110).
[drm:r600_ring_test [radeon]] *ERROR* radeon: ring 0 test failed
(scratch(0x850C)=0xFFFFFFFF)
[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
CF1C (len 62, WS 0, PS 0) @ 0xCF38
[drm:atom_execute_table_locked [radeon]] *ERROR* atombios stuck executing
B67E (len 236, WS 4, PS 0) @ 0xB74B
[drm:atom_execute_table_locked [radeon]] *ERROR* atombios stuck executing
B5DC (len 74, WS 0, PS 8) @ 0xB5E4
[drm:si_dpm_enable [radeon]] *ERROR* si_init_smc_table failed
[drm:radeon_pm_resume [radeon]] *ERROR* radeon: dpm resume failed
The error messages are also shown on connected projectors which is
slightly annoying.
Mostly, after a minute or two the system resumes successfully with the
window manager starting and all applications still running.
However, after more and more suspend/resume cycles the resume process
takes longer and sometimes X11 will crash so that a new session has to
be started.
Best regards,
Thomas
