PVE 4.0 Beta2 KVM stop working after kernel upgrade

[Egner]

Hi,

One of my main nodes that handle my KVM vms stop working after i reboot the server and use the latest kernel version : 4.2.0-1-pve

I facing this error after i have rebooted and trying to start my KVM servers : https://gyazo.com/dcbcae37625f46aed2a7120642f22dcf

Then if i reboot the server again and switch kernel version the KVM just works fine again with : 4.1.3-1-pve

What can be the issue there?

Hardware : DELL M610

 

[Whatever]
