[SOLVED] Slow boot and shutdown/reboot after upgrade

tayko · 2023-12-19 10:28:20

My system boot usually was taking 5-7 seconds, and rebooting/shutdowning was immediate but, recently after I've upgraded the system, boot started to taking almost 10 seconds, and when I run reboot there's a 2 seconds delay. Unfortunately I don't have initramfs-fallback to check if it's the cause of the issue.
I've tried to search something about it but I couldn't find any helpful information.
The most annoying is the 2 seconds delay on shutdown/reboot so I'd be glad if you tell me how I can find out which process creates this delay?

Here's my system configuration.
Linux: linux (6.6.7.arch1-1)
Nvidia driver: nvidia (545.29.06-6)
Filesystem: XFS
Bootloader: efistub
WM: i3wm (without login manager)

systemd-analyze critical-chain

And please post your complete system journal for the previous boot:

sudo journalctl -b -1 | curl -F 'file=@-' 0x0.st

That boot took less than 2 seconds?
This is in line w/ the journal which ends

Do you experience the "slow boot and shutdown" also if you only boot the multi-user.target (2nd link below)?

Thank you very much for pointing out where to look for the problem. It turned out there was a problem with bluetooth.service, I disabled then enabled it, now the system reboots immediately. Boot time also has been fixed.
I assume it happened when I upgraded bluez together with the system, but I still don't understand how it was affecting the system boot time.

graphical.target @1.822s
└─multi-user.target @1.822s
  └─getty.target @1.822s
    └─getty@tty1.service @1.822s
      └─systemd-user-sessions.service @1.742s +39ms
        └─network.target @1.742s
          └─systemd-networkd.service @1.695s +46ms
            └─systemd-sysctl.service @1.593s +79ms
              └─systemd-modules-load.service @361ms +1.200s
                └─systemd-journald.socket @349ms
                  └─system.slice @311ms
                    └─-.slice @311ms

You can see there's only 100ms difference but the total system boot time has been reduced for a 3 seconds. I assume it was something wrong with my usb bluetooth adapter.

That boot took less than 2 seconds?

I was measuring the total system loading time (including the bios).
