Shutdown problems - Failed to wait for process: Protocol error

[pbear]

Haven't read the thread in a while, so apologies if this was tried already, but Rjveral's post suggests a simple workaround. Per Google translate, his (or her) system will shutdown cleanly if swap is disabled first. Easy to test. Run sudo swapoff -a, then shutdown now. If that works, it's relatively easy to create a script or launcher which does the same thing. Just a suggestion. Can't test myself, as I'm not having the problem.

Over a month now and the problem is still here.

For me, some recent update (either yesterday or today) fixed this in Linux Mint XFCE 19.3. Now the system shuts down properly, and also I don't see that "kvm: exiting hardware virtualization" nor the "Protocol errors" messages anymore. Earlier I got rid of by those protocol error messages by some suggestions here, but the shutdown/reboot still got stuck right after that kvm message.

Now everything is fine for me once again. I hope it stays this way.

nope, still have this issue on the 1 machine i've been on since you posted that!

not worked, error continues to appear on shutdown

yep, discovered same here on both machines now that display this error.

[pbear]

Oh well, worth a try. Good luck, ya'll.

[missmoondog]

had previously thought i had this issue on 3 machines but wasn't 100% positive, but now i am.

To save me from skimming all five pages, have you folks tried "raising elephants," i.e., REISUB or REISUO?
Just trying to get a handle on the issue for future reference. Thanks.

no, i haven't. as has been stated many times in this thread, it doesn't cause any issues when shutting down, it's just the fact those messages show up. the only difference i see other than those showing up is that the mint logo doesn't show up when shutting down.

[ericj]

Last time I rebooted I didn't see these messages(s), but during shutdown the "washing machine" Linux logo appeared briefly, which wasn't happening before so may be they just weren't visible.

[pilotbob42]

Now it occurred to me, could this be two separate problems that just happened to appear at the same time for some (including me)?

I see two groups of people reporting about this:

1. Those error messages + shutdown or reboot hangs.

2. Those error messages but everything else is peachy, no shutdown problems. (I'd gather people who have the graphical splashscreen obstructing the shutdown messages don't even see these errors even if they get them; I have changed it so that I always see the messages during boot time and shutdown for just these sort of cases, instead of looking at some Mint logo and wondering why it is stuck).

So if e.g. casper + finalrd causes only those error messages, then it could be something else that causes the shutdown hanging. So I got rid of the error messages by uninstalling casper + finalrd, but that didn't fix the shutdown problem.

Hands up, has the removal of casper + finalrd fixed the shutdown hanging for anyone?

I'm in that first group. I have the error messages AND a hang on shutdown or restart. When I remove casper and finalrd the messages go away, but I still have the hang on shutdown/restart. So, I do think you are on to something. There are two separate issues being discussed here.

And for what it's worth, I'm on Intel graphics so I don't think it's related to any sort of Nvidia issue as some have suggested.

Using the kernel 5.0.0-32-generic the problem was gone!

I was using kernel 5.3.0-53-generic

[karlchen]

Just for the files:

Using the kernel 5.0.0-32-generic the problem was gone.

The kernel series 5.0.0 reached the end of its supported life in February 2020.

Side note about my own machine where I come across the message "Failed to wait for process: Protocol error" during shutdown regularly: It runs on 4.15.0-101. Replacing the supported LTS kernel is not an option, which will manage to creep up into my mind. Never ever.

Recently, when I shutdown I get the following error repeated 5 or 6 times.

[XXX.XXXXXX] shutdown[1]: Failed to wait for process: Protocol error

X are numbers that change every time.

I haven't installed anything new recently, but I did all the updates the Update Manager shows.

I'm having this problem too so I will watch the forum. I am only a basic level user, don't understand code. I have posted elsewhere with shutdown problems but recognised the title phrase from a screenshot.

[kurtburt1001]

I've been using the 5.3.0-51 kernel recently in both Linux 19.3 and LMDE4. There is no hang on restart or shutdown using the -51 kernel.

As soon as I upgrade the kernel to -53 both systems hang with a blank screen on both restart & shutdown. I have to hold the power button to resume.
I've gone back to the -51 kernel on both systems and everything is restarting and closing fine.

Please advise if anyone else has this issue and if there is a recommended course of action.
Thanks!

As far as I know Kurt, as an uneducated user, the only advice is to stay with 51, definitely delete 53, wait for 54 or 55 and just play as safe as you can, keeping at least 3 known good kernels.

[desades]

Hey guys, I was able to solve this problem in myself
I noticed I had a mistake in the trey. The clock window was supposed to show the weather, but it was empty in its place. In the settings I left only the date and the error in turning off resolved.
I did 5 tests after the changes. All 5 ended without error on shutdown.

well, a few days later, the shutdown problem came back. An error occurs when the system is running for more than 30 minutes.
