> Question is why the KIQ is not up and running before we do anything with it? Thank you for the feedback. I completely understand that my patch is just a workaround and not proper engineering - you're absolutely right that the real issue is KIQ being marked as ready before it's actually functional. I don't have experience with GPU drivers and video subsystems, so I'm not familiar with the proper initialization sequence for KIQ. I'd prefer not to keep a workaround for this issue in my tree. Is there a proper fix available, or could you point me in the right direction? I'm happy to test any patches on my AMD Cezanne (Renoir) hardware where I can reliably reproduce the issue after hibernation. Also, regarding hibernation support: you mentioned that hibernation is not generally supported with the driver. Should I expect other issues beyond this TLB flush problem, or is this the main blocker? Thanks for your time, Ionut
