 Posted: Tue Feb 25, 2025 8:31 am Post subject: amdgpu Ryzen 9950X iGPU crashes wiht REG_WAIT timeout |
 |
|
I have actual kernel 6.13.4
Asrock X870E Taichi Lite.
Using iGPU.
It has HDMI and 2 USB-C outpust
I use 3 different displays.
When they all connected (HDMI, USB-C => DVI, USB-C => DP) Display manager often crashes (slim/sddm reloads)
When I dosconnect DP monitor crashes are less frequent.

Hmm. I see usb hub in display reloads. I'll try disconnect this display, may be the problem is this display... |

For a bleeding-edge kernel version, you should also accept ~amd64 at linux-firmware. Did you do that?
My system uses a Zen4 Ryzen and is running 2 DP Monitors on iGPU via DP daisychain. Since kernel release >=6.10 its running perfectly stable. Before, it was horrible... amdgpu crashes and spontaneous system reboots.
Maybe future kernel and firmware versions may help in your case.
What i can also advise you: stay away from power cords with your DP cables or display cables in general. They are emitting EM interference that caused my monitors to regularly crash and loosing connection. Some monitors are likely more sensitive than others but it's always a good decision to separate data cables away from power cables. Especially cable management where they are in direct proximity to each other caused this problem for me. Maybe this helps you, too. |

AMDGPU is very volatile, I didn't have reliable wake up from sleep since 6.1.57 or something like that. I was stuck with 6.1.91 which at least offered almost reliable wake up from sleep when plugged in. Only recently someone pointed out on the forums they had this issue solved in 6.13. They solved one, but maybe created others...
Best Regards,
Georgi |
