From the github acpica discussion is looks a lot like there was no real progress. And drivers/acpi/acpica/evevent.c in next looks unchanged; and from searching for ACPI_EVENT_PCIE_WAKE on lore it also looks like neither the fix nor a revert was posted. But I might be missing something. /me still hopes we can get this fixed somehow before Linus releases 6.3 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.
