https://bugzilla.kernel.org/show_bug.cgi?id=209079 --- Comment #4 from Sean Christopherson (sean.j.christopherson@xxxxxxxxx) --- GFP_DMA32 is a flag that forces a memory allocation to use physical memory that is 32-bit addressable, i.e. below the 4g boundary. Using GFP_DMA32 is relatively uncommon, e.g. KVM uses that flag if and only if KVM is using or shadowing 32-bit PAE paging. The latter case (shadowing) is what is triggered if NPT is disabled. Can you try trying running with "kvm_amd nested=0 avic=1 npt=0" and/or "kvm_amd nested=0 npt=0" on v5.8.7? I'd like to at least confirm that whatever was breaking your setup was fixed between v5.8.0 and v5.8.7, even if we don't bisect to identify exactly what patch fixed the bug. -- You are receiving this mail because: You are watching the assignee of the bug.
