Arch hangs on reboot

Disclaimer
I've sporadically experienced this issue on two Dell laptops, however it doesn't seem to be laptop specific.
I'm unable to reliably reproduce it as it only happens sporadically.

Issue
No matter what kernel I run (be it lts, hardened or standard), on some reboots I experience a system hang for
about 90 seconds witch black screen and an underscore cursor blinking in top left corner. After that, system
reboots.

Additional Info
UEFI install
Laptop Dell Latitude 5501, i7 9th gen, no nvidia graphics, only Intel UHD 630.

At first I thought this has to do with PCI, that's why I added this to mi grub conf (and updated grub of course):

GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 quiet reboot=pci acpi=force"

That didn't help though.

Logs

Here's journal log from the last reboot during which this issue occurred.

journalctl -r

There's approximately 90 second delay between these two entries:

Jul 17 14:08:48 arch systemd[565]: Stopped target Main User Target.
Jul 17 14:07:20 arch systemd[565]: pulseaudio.service: Succeeded.

Could this be caused by pulseaudio?

Re: Arch hangs on reboot

Looks like a shutdown issue. The 90 seconds is the default timeout for services that don't respond.

Jul 17 14:08:48 arch systemd[566]: pam_warn(systemd-user:setcred): function=[pam_sm_setcred] flags=0x8004 service=[systemd-user] terminal=[] user=[patres] ruser=[<unknown>] rhost=[<unkno>
<snip>
Jul 17 14:02:35 arch systemd[565]: var-lib-docker-overlay2-opaque\x2dbug\x2dcheck383479491-merged.mount: Succeeded.
Jul 17 14:02:05 arch gpasswd[372517]: patres failed to add user patres to group docker: Permission denied

That's  a strong indication towards a docker /systemd-user issue, maybe the truncated line has more useful info then is visible.
check https://wiki.archlinux.org/index.php/Sy … ing_output for ways to wrap instead of truncate journalctl output .

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?
Try clean chroot manager by graysky

Re: Arch hangs on reboot

I would suspect systemd-user, since I've only installed docker today and this issue was prevalent before.
Untruncated journal doesn't seem to offer much help.

Jul 17 14:08:48 arch systemd[566]: pam_warn(systemd-user:setcred): function=[pam_sm_setcred] flags=0x8004 service=[systemd-user] terminal=[] user=[patres] ruser=[<unknown>] rhost=[<unknown>]

Edit
I've just experienced the same issue on shutdown with hang taking place between the same two entries:

Jul 18 09:49:27 arch systemd[573]: Stopped target Main User Target.
Jul 18 09:47:59 arch systemd[573]: pulseaudio.service: Succeeded.

And this is how journal looks upon rebooting without delay/hang:

Jul 18 10:13:18 arch systemd[557]: pam_warn(systemd-user:setcred): function=[pam_sm_setcred] flags=0x8004 service=[systemd-user] terminal=[] user=[patres] ruser=[<unknown>] rhost=[<unknown>]

Re: Arch hangs on reboot

Did you solve this issue?, I am also experiencing it for a while now.

Re: Arch hangs on reboot

It would be better to find out why it is happening, but temporary you could change that 90s timeout to something lower in /etc/systemd/system.conf uncomment and change value DefaultTimeoutStopSec=90s . Details in 'man system.conf.d'. Also see:
