I'm also waiting for updates. I can't even use any of the 4.8x - all of them have virtualization setting bug.

So, what is this mysterious "Virtualization bug" you are speaking of? I am currently running 4.81 on my 1700x, and directly after flashing, yes, my VirtualBox didn't run - SVM was disabled in bios by default. Simply enable SVM under "CPU Configuration" in the bios and all is working fine now.

If your 'bug' is that 'SVM' is by default disabled in this beta bios and you forgot to enable it, then ROFL.

My virtual machine works fine right now. Lots faster than when I was still on P1.40 bios.

That didn't work for me. Enabling SVM had no effect last time I tried.

I've read your previous posts and you too seem to mention it is application specific? Obviously if it worked on older BIOS versions, they changed something, maybe some obscure setting.

I'm using Oracle VirtualBox and it's working right now, 1700x L4.81 bios on x370 Taichi.

It's a bug in Linux due to Bios advertising Secure Encrypted Virtualization(SEV). SEV is only used for epyc processors/ ryzen pro processors(tsme)
