I have the same problem (minus the external displays). I am running Ubuntu 20.04, kernel version 5.4.0-58-generic. On resume from suspend, the kernel spews out the following messages:
kernel: [drm:atom_op_jump [radeon]] *ERROR* atombios stuck in loop for more than 5secs aborting kernel: [drm:atom_execute_table_locked [radeon]] *ERROR* atombios stuck executing CB56 (len 62, WS 0, PS 0) @ 0xCB72 kernel: [drm:atom_execute_table_locked [radeon]] *ERROR* atombios stuck executing B716 (len 236, WS 4, PS 0) @ 0xB7E3 kernel: [drm:atom_execute_table_locked [radeon]] *ERROR* atombios stuck executing B674 (len 74, WS 0, PS 8) @ 0xB67C kernel: [drm:si_dpm_enable [radeon]] *ERROR* si_init_smc_table failed kernel: [drm:radeon_pm_resume [radeon]] *ERROR* radeon: dpm resume failed -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1838678 Title: radeon kernel driver fails to resume from suspend Status in linux package in Ubuntu: Expired 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.
