All is good if we manually avoid it qemu-kvm [...] -append ioapic_ack=new KVM IOAPIC never gets EOI. I'll take a look where the problem is. -- You are receiving this mail because: You are watching the assignee of the bug.-- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
