Bug Description
Executing
$ cat /proc/acpi/
usually returns one line, like this:
state: open
But recently it has also started to spew quite a lot of data to kern.log. On this host and this kernel rev, I see 177 lines in the log from this one access.
I've attached a file with what appears in kern.log from one such access.

It is just possible that this bug is related to this other bug, a possible regression in the i915 driver: lists.freedeskt op.org/ archives/ intel-gfx/ 2014-May/ 045519. html

The symptoms are similar even if the circumstances are not exactly the same. But since I'm explicitly reading the lid state, the circumstances may actually be quite close.
