The culprit seems to be the patch KVM: x86: update %rip after emulating IO with the upstream commit 45def77ebf79e2e8942b89ed79294d97ce914fa0. Reverting this alone fixed the problem. The report is found at openSUSE bugzilla: https://bugzilla.suse.com/show_bug.cgi?id=1132694 Is there already a followup fix? If not, we need to revert it from stable, at least. thanks, Takashi ^ permalink raw reply [flat|nested] 11+ messages in thread

Those KVM tests being integrated by Linaro into the stable testing process can't come fast enough, I was told yesterday that they would be in there "soon"... thanks, greg k-h ^ permalink raw reply [flat|nested] 11+ messages in thread

I'd be surprised if 5.1-rc* changes anything relative to 5.0.x, the commit in question is fairly isolated and specific. Can we get the Qemu version and command line that is being run? ^ permalink raw reply [flat|nested] 11+ messages in thread

The reporter confirmed that the problem is present with the latest 5.1-rc kernel, too. FWIW, it's a Ryzen system.

My best guess at this point is that the issue is related to an older version of Qemu or a specific emulated device, but without additional details we're stuck. ^ permalink raw reply [flat|nested] 11+ messages in thread
