sr-iov invoke system reboot

[世祁]

Dears, I use sr-iov vf for docker network device by kubernetes, but there has a bigger probability of system reboot

syslogs record nothing, and only happened when there are release & allocate VF

what should I do for solve this problem?

My environment:

BIOS already enabled VT-d and SR-IOV global enable

os is ubuntu 16.04, kernel version 4.10, options is

BOOT_IMAGE=/vmlinuz-4.10.0-35-lowlatency root=UUID=xxxx ro cgroup_enable=memory swapaccount=1 intel_iommu=on iommu=pt

set max_vfs to 63

echo 63 >/sys/class/net/enp4s0f1/device/sriov_numvfs

Hi Scholsles,

Thank you for writing to Wired Communities. What is the exact X520 network adapter you have?Can you type lspci -nn | grep -i 'Ethernet Controller command to share the device and vendor ID output? Please elaborate more about the release and allocate of VF(virtual function)Where did you download the driver? Please feel free to update me.Thanks,Sharon
