Title:
kernel oops - kvm guest started at boot time
Status in linux package in Ubuntu:
Confirmed
Status in linux source package in Xenial:
New
Bug description:
[SRU Justification]
[Impact]
ppc64le system OOPSes shortly after boot when KVM guests are started.
[Fix]
Cherry-pick patch e47057151422a67ce08747176fa21cb3b526a2c9
[Testcase]
Tested at IBM - boot a machine with a KVM guest configured to start at boot.
Without this patch, observe OOPS, with this patch, observe no OOPS.
[Regression Potential]
Patch is contained in arch/powerpc; so regression potential limited to that
arch. Patch accepted to kernel stable trees, suggesting others also believe it
to be of low risk.
