[Kernel-packages] [Bug 1702768] Re: Ubuntu 17.04 KVM: stack trace generated when enabling SRIOV in power

2017-07-10 Thread Joseph Salisbury

I built a test kernel with a pick of commit 377aa6b0efba.  The test
kernel can be downloaded from:

http://kernel.ubuntu.com/~jsalisbury/lp1702768/

Can you test this kernel and see if it resolves this bug?
