Hi Joe,

Thanks for the report.

I thought I was running the livepatch tests, but looks like somewhere
along the line my kernel .config lost CONFIG_TEST_LIVEPATCH=m, so I have
been running the test but it just skips. :/

I can reproduce the failure, and will see if I can bisect it more
successfully.

cheers
