Hi Rafael, There are 2 bug reports: 1. Brightness up/down key-presses no longer working on LG laptop (acpi-video related): https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx/thread/V2KWAGZIAX4TOWPCH6A6FSIT66PR3KMZ/ 2. EC related ACPI errors and bad performance: https://bugzilla.redhat.com/show_bug.cgi?id=2298938 Both of which started with 6.9.7 which has the 2 commits related to "EC: Install address space handler at the namespace root" from 6.10 backported: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/drivers/acpi?h=v6.9.7&id=2b2b0ac1533d790690d6d28899f01a2924d54d4d https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/drivers/acpi?h=v6.9.7&id=9750135f2f326879889ed60ccd68b96572dfa6ee i have build a test 6.9.9 kernel with these 2 reverted and 1. is confirmed to be fixed by reverting these 2 commits. Although the user does report an IRQ storm on the ACPI IRQ (IRQ 9) related to thunderbolt after this. I have not yet got confirmation that the second bug is also resolved by the commits. Either way it looks like we need to dig into this and figure out what is causing these EC related regressions. Regards, Hans
