| |
The laptop is a 2-year-old macbook Pro with retina display.
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 <matthew.garrett@nebula.com> 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?
PS: the bisect log:
