Thanks! Patch does not fix the issue. Patched 4.7-rc5 and 4.6.2. Issue still exists. Please look for the VMCS dump in /var/log/messages or dmesg and paste it here. Thanks! I believe this is what you are looking for?

The patch has not yet hit Linus's tree, you need to apply it manually. Very strange, I applied it to the latest mainline and got the same issue. It is entirely possible I am doing something wrong. I apologize if I wasted your time, I'll try again on an LTS kernel and see if I can get it working. Sorry about that. Thanks! |
