Suspend/hibernate freezes with radeon driver loaded on AMD/ATI hybrid graphics

[Saurav]

On at least Ubuntu 15.10 and 16.04 with the radeon driver (version 7.5.0+git20150819-0ubuntu1 on 15.10, version 7.6.1-1ubuntu2 on 16.04) trying to suspend or hibernate a Lenovo G50-80 with Intel HD Graphics 5500 (Broadwell GT2) and Advanced Micro Devices [AMD/ATI] Sun XT [Radeon HD 8670A/8670M/8690M / R5 M330] freezes the system when the radeon driver is loaded even if it is not in use. Turning off discrete graphics using the BIOS settings and using only the integrated Intel chip so that the radeon driver is not loaded does not cause this problem. Also, this problem does not occur on Ubuntu 14.04.4 using the kernel and X stack (LTS Enablement Stack) from 15.10 (Wily) even with the radeon driver loaded.

There is a message from the radeon driver during boot, "radeon 0000:04:00.0: VCE init error (-22)." which is an upstream issue occurring on other distributions too and is reported at https://bugs.freedesktop.org/show_bug.cgi?id=92722. However, even if the radeon driver is loaded, suspend/hibernate does not freeze on, e.g., Fedora 23 and, as mentioned above, even Ubuntu 14.04.4. I have tried using S1 instead of S3 sleep to no avail.

I'm not sure if this is a duplicate. My problem occurs only if the radeon driver is loaded (although the AMD GPU need not be in use). Both suspend and hibernate work fine for me if the radeon driver is not loaded, e.g., by disabling the AMD GPU in the BIOS settings. I did not find much information on display hardware in the other bug report.

[Saurav (saurav1)]

I have one integrated Intel GPU and one (muxless) discrete AMD GPU, but xrandr --listproviders shows two discrete GPU entries along with the integrated GPU.

[Saurav (saurav1)]

After the latest updates, the duplicate entry for the discrete GPU has gone. It now correctly shows only two GPUs in total.
