Quoting from https://bugzilla.kernel.org/show_bug.cgi?id=217069 : An issue that looked like a network bug was now bisected and it turns out it's cause by 5c62d5aab875 ("ACPICA: Events: Support fixed PCIe wake event") which Huacai Chen provided. Could you take a look at the ticket linked above? FWIW, the whole story started like this: >> Ivan Ivanich 2023-02-22 00:51:52 UTC >> >> After upgrade to 6.2 having issues with wake on lan on 2 systems: - >> first is an old lenovo laptop from 2012(Ivy Bridge) with realtek >> network adapter - second is a PC(Haswell refresh) with PCIE realtek >> network adapter >> >> Both uses r8169 driver for network. >> >> On laptop it's not possible to wake on lan after poweroff On PC it's >> not possible to wake on lan up after hibernate but works after >> poweroff >> >> In both cases downgrade to 6.1.x kernel fixes the issue. Meanwhile a few others that ran into the same problem with NICs from different vendors joined the ticket Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat) -- Everything you wanna know about Linux kernel regression tracking: https://linux-regtracking.leemhuis.info/about/#tldr If I did something stupid, please tell me, as explained on that page.
