--- Comment #7 from Robert Strube rstrube@gmail.com --- Thanks for the suggestions! I took your advice and commented out the Vega M device IDs located here: /drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c
These are the lines of code that I commented out. /* VEGAM */ {0x1002, 0x694C, PCI_ANY_ID, PCI_ANY_ID, 0, 0, CHIP_VEGAM}, {0x1002, 0x694E, PCI_ANY_ID, PCI_ANY_ID, 0, 0, CHIP_VEGAM},
This did indeed cause my Vega M to not be initialized, *but* the problem I'm having with the eGPU remains. So it appears you were correct and my hunch that the Vega M is interfering with the eGPU initialization was incorrect. I'm back to square one...
I uploaded a new dmesg log for this kernel, perhaps with the Vega M out of the equation you might see something new?
Thanks! Rob
