Is this still an issue? Some workarounds are documented here: https://askubuntu.com/questions/1028883/ubuntu-18-04-systemd-udevd-uses-high-cpu-conflict-with-wifi (In reply to Mike Pagano from comment #1) > Is this still an issue? Some workarounds are documented here: > > https://askubuntu.com/questions/1028883/ubuntu-18-04-systemd-udevd-uses-high- > cpu-conflict-with-wifi Yes, still an issue on gentoo-sources-4.19.x. I will try these workarounds/fixes at the next kernel release and see if they work - thanks for sharing. TBH this is now quite an old system and with Intel throwing it to the kerb with no further microcode updates, I don't know if there is enough of a user base (in any distro) to merit fixing it. Hi, I just tried gentoo-sources-5.4.28 and the problematic code has now been fixed. WiFi works fine again. -- Regards, Mick |
>=gentoo-sources-4.14.x cause bind/unbind uevents on hardware with BCM2046B1 mini-card. Reproducible: Always Actual Results: CPU is pegged at 100% with the kernel looping bind and unbind of the USB mini-card. Would it be possible to back port the patch provided in the above referenced URL, to revert the bind/unbind kernel commit entries? On the 4.14.x releases the lines requiring removal are different to what is shown in the URL.
