It looks like there's also a fix for that nested virtualization bug causing host reboots on Ryzen 7000/8000 CPUs [0]. It's nice to see that the cause appears to be known and that it's being addressed (even if the kernel here is technically not at fault).
Apparently this problem is caused by a CPU erratum (or unsupported functionality?) with some (many?) BIOSes still reporting the broken/unsupported instructions (VMLOAD/VMSAVE) as being available with these CPUs, at least according to some discussion about it on the LKML [1].
