See if in the BIOS you can switch between S3(STP) and S1(POS) in power management.

I would try setting a grub boot parameter to fix this.

Try either of the following fixes to see if they correct your issue.

You could try the"amd_iommu=on iommu=pt" boot options if you have an AMD CPU.

Edit /etc/default/grub and add amd_iommu=on iommu=pt to the the end of the load line:

GRUB_CMDLINE_LINUX=“amd_iommu=on iommu=pt”

Or:

You could try the intel_iommu=on iommu=pt boot options instead (if you have an Intel processor).
