[SOLVED] Process scheduling seems to stop?

Sometimes, when I boot up, things run normally, I start X, and then at some point which I can't figure out how to identify, processes stop getting scheduled properly. I can launch new ones, but they never seem to be allocated any cpu time; they simply hang with no output.

When I try to shut off the computer at this point, there's a service which does not shut off called "realtimekit policy scheduling service", or something similar.

I haven't figured out how to get the logs of the rtkit daemon from times that this happens -- launching systemctl hangs.

Sometimes, booting up is totally fine and nothing happens, though.

I've never debugged an issue like this before, any help would be appreciated.

TIA

Re: [SOLVED] Process scheduling seems to stop?

We'll need some hard data on the situation - eg. a complete system journal for an affected boot.
But rtkit sounds pulseaudio related.

Re: [SOLVED] Process scheduling seems to stop?

Here's a journalctl -u from the boot where the problem occurred as soon as I logged in: http://sprunge.us/MYIvzE

Here's a journalctl from a boot where it starts up correctly, I put the laptop to sleep, and then the problem appears afterards: http://sprunge.us/diFWmW

It seems like PulseAudio is indeed having some trouble, but it's far from the only one.

For example, this error here:

Feb 17 20:02:03 mongoes dbus-daemon[330]: [system] Activating via systemd: service name='org.bluez' unit='dbus-org.bluez.service' requested by ':1.20' (uid=1000 pid=664 comm="/usr/bin/pulseaudio --daemonize=no --log-target=jo")
Feb 17 20:02:03 mongoes dbus-daemon[330]: [system] Activation via systemd failed for unit 'dbus-org.bluez.service': Unit dbus-org.bluez.service not found.
Feb 17 20:02:03 mongoes pulseaudio[664]: stat('/etc/pulse/default.pa.d'): No such file or directory
Feb 17 20:02:03 mongoes systemd[550]: Started Sound Service.
Feb 17 20:02:03 mongoes pulseaudio[664]: GetManagedObjects() failed: org.freedesktop.systemd1.NoSuchUnit: Unit dbus-org.bluez.service not found.

But, there seems like there are a _lot_ of errors... Should I be concerned?

Thanks.

Oh, and I should've mentioned already, this is a Framework laptop w i7 1165 g7.

I read through the arch wiki page and couldn't find anything related to this on it, though.

Re: [SOLVED] Process scheduling seems to stop?

Okay, I think I might have fixed the problem.

I had iwd and NetworkManager running simultaneously, and that was causing problems for the network card, and I didn't have the bluetooth service enabled, which was causing the

GetManagedObjects() failed: org.freedesktop.systemd1.NoSuchUnit: Unit dbus-org.bluez.service not found.

error (which I found here https://bbs.archlinux.org/viewtopic.php?id=172163 ).

I've rebooted a few times and it's started as expected, as well as put the laptop to sleep and it seems to work properly.

Thanks for your help so far, and I'll update the post if the problems reappear.
