reboot/shutdown taking very very long....

Hi,

for a couple of months, I noticed that a reboot or shutdown takes often very long..between 1-2 minutes.
The startup/booting however only takes a couple of seconds.

I noticed during the shutdown/reboot message it stalls at a message something along the lines of "Updating man-db cache" or something similar.
Even if I didn't run a pacman update (sudo pacman -Syu')

This step is reproducible, however I would like to know the reason why it sometimes takes very very long, and other times it only takes a few seconds.
Has anyone experienced something similar? I know this problem description sounds rather vague
but to me it seems like it's halting somewhere or waiting for a time-out during the shutdown process.

How would one go about to debug this?

I appreciate any help on this.

best,
theresa

Re: reboot/shutdown taking very very long....

AFAIK, man-db is updated during boot and not during shutdown.

Please post the output of

journalctl -b -1

Also, try running mandb manually and see if it turns up anything suspicious.

Hi,

I've pasted it over here:

I know plasmashell and other kde applications log a lot of times.... please excuse the mess!

I was running mandb manually, unfortunately the output is in german which probably wouldn't make a lot of sense to you.... but I think it looks fine, nothing suspicious.

Re: reboot/shutdown taking very very long....

micsnare,

you got several kernel calltraces in that log.
They all look like there's a problem with the intel kernel module, possibly with DP-connected monitors.
If you do have monitors on a Display Port connection,could you try switching them to hdmi or dvi ?

Lone_Wolf,

I've indeed got 2 external monitors, however they are connected through HDMI and VGA.

mini-HDMI to HDMI
mini-VGA to VGA

due to the small ports on my laptop...

so, actually I have no idea where these kernel messages come from
