Comment 9 for bug 1755268

Hi, I can't build new mellanox drivers for new kernel, so I used default one:

    # ethtool -i eno1
    driver: mlx4_en
    version: 4.0-0
    firmware-version: 2.42.5004
    expansion-rom-version:
    bus-info: 0000:11:00.0
    supports-statistics: yes
    supports-test: yes
    supports-eeprom-access: no
    supports-register-dump: no
    supports-priv-flags: yes

After creating virtual machine, my kernel was stuck with these messages:
    [ 2170.511433] kvm [28464]: vcpu0, guest rIP: 0xffffffff810644d8 disabled perfctr wrmsr: 0xc2 data 0xffff
    [ 2170.963166] ------------[ cut here ]------------
