I use a dockapp called wmlaptop2 (http://repo.or.cz/w/wmlaptop2.git) which, among other things, displays battery information (% of charge remaining etc). With the kernel v3.17 the battery information stopped working and it still does not work in the latest v3.19-rc1. Looking at what wmlaptop2 does I noticed that one entry inside /sys/class/power_supply is not present in a bad kernel. In a good kernel: [mafra@linux-g29b:~]$ ls /sys/class/power_supply/ ADP1@ BAT0@ but in v3.17 onwards there's no BAT0@ entry: [mafra@linux-g29b:~]$ ls /sys/class/power_supply/ ADP1@ I bisected the problem to this commit: commit 7bc5a2bad0b8d9d1ac9f7b8b33150e4ddf197334 Author: Matthew Garrett Date: Sat Sep 20 13:19:47 2014 +0200 ACPI: Support _OSI("Darwin") correctly Is there anything else I can do to help fixing this?
