Comment 104 for bug 2039868

Hello, I'm having this same issue with my thinkpad z16 laptop, Ryzen 6850H and Radeon RX 6500M graphics card.

I do not use the laptop for gaming but for audio and video editing. I have not had trouble with any video editing software but I can easily reproduce the issue by loading up Ardour or Mixbus32C and either leaving it alone or working. After 15 minutes the screen freezes although audio will continue for a time. At this point Ardour or Mixbus will close and I can continue using the machine. If I load up either program again it will fail again, usually within a couple minutes and the whole laptop will freeze up until I ctrl-alt-F2 to get to a terminal prompt.

The issue always happens when Im recording audio with an HDMI device attached and 90% of the time without HDMI

I will attempt to set this kernel parameter amdgpu.mcbp=0 and report back.
