4.1.0 .config

On kernels  3.17.8, 3.18.11, 4.0.5, & 4.1.0 there is no /sys/class/power_supply/BAT0. It exists on 3.14.1.

I need to use 3.17 or newer for thunderbolt hotplug support. acpi battery is broken for these. Can't query how much battery I have. That's almost as annoying as not being able to use ethernet (adapter via thunderbolt); maybe even more annoying.

Lv,

Do you have battery information on the MAC pro retina 13?
Comment 6 Lv Zheng 2015-07-06 04:47:21 UTC 
There is /sys/class/power_supply/BAT0 and my kernel is 3.19.0-15-generic.
The model # of this test platform is MacBookPro A1502.
Have you tried recent Ubuntu images?

Thanks and best regards

I have no idea, maybe use git bisect to find the offending commit?

It's not annoying enough yet to warrant hours spent on bisecting and recompiling and restarting my main work computer when I should be working. It's getting there though...

You need CONFIG_ACPI_SBS in your kernel config on newer kernels.
