[Bug 1218480] New: NetworkManager: stuck at "NetworkManager state is now CONNECTING", using wlan0, booting laptop with battery
https://bugzilla.suse.com/show_bug.cgi?id=1218480 Bug ID: 1218480 Summary: NetworkManager: stuck at "NetworkManager state is now CONNECTING", using wlan0, booting laptop with battery Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.5 Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Network Assignee: songchuan.kang@suse.com Reporter: antonio.feijoo@suse.com QA Contact: qa-bugs@suse.de Target Milestone: --- Found By: --- Blocker: --- Issue detected after upgrading laptop Lenovo ThinkPad P15 G2 from Leap 15.4 to 15.5. When trying to boot the laptop using only the battery, NetworkManager is not able to connect to the wifi and the system bus (dbus-daemon) becomes unresponsive, leaving the system unusable, and the only way to shut down the laptop is holding the hardware power button. I'm not sure if this is a kernel bug, so please reassign it accordingly if you find that, but it's reproducible with kernel 5.14.21-150500.55.39-default (kernel-firmware-20230724-150500), and also with kernel 6.6.7 (kernel-firmware-all-20231214-lp155) from Kernel:stable:Backport. -- You are receiving this mail because: You are on the CC list for the bug.

Looks like something related to the TLP package and the feature that disables wi-fi card while on battery. Uninstalling the package the problem the problem does not occur anymore.
After removing the tlp package (kudos to Andrea), the NetworkManager is able to connect using the laptop battery only. So, we have 2 problems here: - The default installation of the tlp package from the hardware repo in Leap 15.5 (tlp-1.6.1) blocks the usage of the wifi when the system is battery powered only. This didn't happen in Leap 15.4 (I can't remember if I was using the default tlp-1.4.0 or the package from the hardware repo...). I guess the package from the 15.5 main repo (tlp-1.5.0) should not have this issue, but after a week with continuous problems to be able to work with my laptop, this is something I don't want to test right now.. - The NetworkManager floods the system bus in that case, leaving the system in an unusable state. -- You are receiving this mail because: You are on the CC list for the bug.

To collect them, add the following to /etc/NetworkManager/NetworkManager.conf, restart NetworkManager, reproduce this issue and attach the output of "journalctl -b" here.
