AMD S7150 x2 GPU and Asus Pro WS WRX80E-SAGE SE WIFI II mainboard compatible?


Apr 27, 2021
Hello folks,

I have been trying for a week without success to get the mentioned graphics card to work on the Asus mainboard.
I followed the instructions below:
I have also tried without DKMS.

But always the same problem - when trying to load the driver with modprobe gim, the server crashes and reports:
watchdog: BUG: soft lockup - CPU#26 stuck for 27s! [modprobe:1747]

Have SR-IOV and IOMMU and over 4G bar support enabled in the bios.
In the Asus Bios I have Legacy and UEFI set in boot options.
I have not found any other options in this bios to initialise the legacy boot ROM while using NVME via UEFI boot.
Is it perhaps too new for that old graphic card?
Was this still possible with the predecessor Asus Pro WS WRX80E-SAGE SE WIFI (without II at the end)?

I'm at the end of my tether.

Asus support blames the error on the third-party driver and whether AMD can give me a satisfactory answer remains to be seen.

Can you tell me your motherboards that have been successfully tested with this graphics card?
I have 4x S7150 x2 cards.
I would prefer motherboards with 6x or 7x PCIe x16.
Does anyone have any experience, perhaps even with the same mainboard?

Is the mainboard compatible?

Thank you.
