Phoronix: Some Older AMD GPUs + Intel Alder Lake Is Causing ASPM Problems For Linux Users

Older AMD GPUs paired with Intel Alder Lake Platforms is leading to hangs during suspend/resume cycles so a patch is pending for the Linux kernel to disable Active State Power Management (ASPM) in such combinations...

Intel hardware having issues with AMD hardware. What a coincidence!

Yeah, it's not like AMD hardware doesn't have issues with AMD hardware.

One of my colleagues gave up on AMD after his Polaris GC and Ryzen 1 did never work on suspend or cored during video playback with low frame rates. All this stuff worked at some point, than it never did again. For about a year he was frequently checking the latest build, hoping for improvement, but well never happened. Now he is waiting for a dedicated Intel GC, hoping all get better again. Than lucky AMD GC user here under Linux. Though RX 5700 generation, and not so happy about the missing ROC support, until recently.

Yeah, on my machine with an AMD APU I can crash the amdgpu driver just by watching 2 videos using hardware video decoding.

Yes, perhaps they should just write the code better, as amdgpu crash a lot when nearly idling on Vega too.

Did you report that? Sounds easy enough to reproduce and a common enough use case for devs to want to pick up on that.

There already is a ticket for like half a year now. https://gitlab.freedesktop.org/mesa/mesa/-/issues/5359

Not sure if this firmware update will fix your problem but it definitely sounds like AMD is still working on getting VCN stable down at the firmware level: https://www.phoronix.com/scan.php?pa...VCN-Multi-Hang

Yeah that seems to have fixed it finally.
