Reproducible on 4.16-rc3 and 4.4.20 using defconfig - the failure it's
intermittent, but i could reproduce it 100% if i boot loop the kvm instance 
(it usually shows up in less than 10 iterations but i tested 32 boots before
marking it good).

Anything else i can do to help debug this?
If you could share the crash log, that would be helpful.

The patch that Ard linked to should resolve that particular crash.
I see this is a 4.13-based kernel. Is the source tree available anywhere?
