I installed Debian 11 (Bullseye) with GNOME 3.38.5 (Wayland), LINUX kernel Linux version 5.10.0-11-amd64 (gcc-10 (Debian 10.2.1-6) 10.2.1 20210110, GNU ld 2.35.2) #1 SMP Debian 5.10.92-1 (2022-01-18) on a USB stick, and am using it with an ACER Aspire 514 laptop.
This operating system has worked excellently for months, but for the last 2 days has suddenly been taking a very long time to boot. The cause of the delay can be seen from the syslog: Feb 28 10:09:30 cpe-67-241-65-193 systemd[1]: Started GNOME Display Manager. (The above is the last line on the verbose boot log printed on screen during boot process) (omitted next lines from network manager, & kernel, about setting up network & loading audio firmware, etc.) Feb 28 10:09:31 cpe-67-241-65-193 systemd[1]: Created slice User Slice of UID 119.

The same 90 sec delay then occurs again after any user enters his password (at 10:11:46): Feb 28 10:11:46 cpe-67-241-65-193 systemd[1]: Created slice User Slice of UID 1003.

The first 90 sec. delay only occurs on initial startup, & the second only when any user logs in (the problem is not particular to UID1003, but occurs for all UIDs 100[0-5]. Once the machine has booted & the user is logged in, it functions normally with no observable problems. I do not know what caused this, but it occurred right after I: > allowed the installation of the latest software update (some lib files, the names of which I unfortunately did not record) > installed the ufw firewall package. I would be very grateful for any information about how to resolve this (apart from re-installing the system) or even any reference that might give information about how I might resolve this problem. (I have looked at the systemd.service man page, but although I have experience with the unix command line, I have only been using Debian since Nov. 2021 & am not familiar with its system administration, & I could find no information there about this problem.)
