[SOLVED] udevd cannot start, core dump

I performed a full system upgrade on my laptop the other day (had not done for about two weeks prior) - included a kernel update so I performed a reboot and on next boot discovered udev is failing at startup (or if attempting to start service manually) journalctl reports:

systemd-udevd-kernel.socket: Failed with result 'service-start-limit-hit'.

I assume this means it is not loading the relevant modules for networking either because I also have no network connectivity, so I cannot even do another pacman -Syu and hope to upgrade my way out of the problem.

Any ideas on what is wrong or how to fix would be most appreciated. Many thanks.

I'm sorry I do not follow. That does not appear to be a valid command.

I tried asking over at the systemd mailing list but they just said it was glibc packaging error on the Arch side, though that seems unlikely considering the package (2.31-5) is almost 3 weeks old.

Re: [SOLVED] udevd cannot start, core dump

I was able to use this wiki page to manually load the required modules for my wireless adapter (brcmfmac, lib80211) and from there get online run another pacman -Syu which completed without issue.

https://wiki.archlinux.org/index.php/Broadcom_wireless

However on reboot the issue remains.

Could this be related https://bbs.archlinux.org/viewtopic.php?id=256334 ?

Although udevd seems to be waiting for a different piece of hardware to come up.
