Title:
System reads
For developing a test case for this it would be really helpful if you
could copypaste the output of this command:
grep -r . /sys/class/power_supply/*hid*
Thanks!

`grep -r . /sys/class/power_supply/*hid*` seems to run forever.
Is there other command that can run sooner?

Title:
System reads bluetooth input
Hm, it should take no time at all, so it seems trying to read a
particular attribute triggers a kernel bug. Could you start with
ls -lR /sys/class/power_supply/*hid* ?

@pitti,
I can run `grep -r . /sys/class/power_supply/*hid*` in Ubuntu 13.04 without any
problem.
But when I run it in Ubuntu 12.04, it shows some messages like grep: warning:
...: recursive directory loop.
It seems to be another bug of grep in Ubuntu 12.04. :P
