I found out that doing kill -38 <your_pid> makes it run again, so we're likely hanging somewhere while holding qemu_mutex. The state of the process is "D", so we're holding qemu_mutex, and then calling something that can block. It's hard for me to believe that this patch introduced it. At best, it might have made it more likely. Also, I also verified that it sometimes takes a while until it happen for the first time. Are you sure this is the first patch that makes it happen? -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
