Managing AMDGPU power state causes crash

[FishusOne]

Randomly I find that USB devices will disconnect, and I can see occasional graphical flickers on the screen. Speaking to Framework support, and looking at the logs, it seems that there is a mismatch in the expectation of which firmware is in use for the GPU. The kernel driver expects 0x35, but 0x40 is installed.

Adding amdgpu.runpm=0 to the kernel parameters has meant I havent noticed a USB disconnect since, and seems like a functioning work around.

• System: Framework Laptop 16 (AMD Ryzen AI 300 Series)
• Radeon RX 7700S
• BIOS: 03.04
• Kernel: 6.18.12-1-MANJARO
