[Bug 1752236] Re: Ubuntu 18.04 - Performance: Radix page fault handler bug in KVM

2018-03-05 Thread Joseph Salisbury
I built a test kernel with the patch referenced in the description.  The test 
kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1752236

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

Note, to test this kernel, you need to install both the linux-image and
linux-image-extra .deb packages.

Thanks in advance!
