/proc/acpi/button/lid/LID/state sends application to D state...

When an application tries to access  /proc/acpi/button/lid/LID/stated it goes to D state.

Eg. cat /proc/acpi/button/lid/LID/stated

F   UID   PID  PPID PRI  NI    VSZ    RSS  WCHAN  STAT   TTY        TIME    COMMAND
0     0  5625  5574  20   0   3944   224  acpi_e     D    ?        0:00     cat state

2.6.39-ARCH
acpid 2.0.10-2

As result of the above is that my laptop doesn't goes to sleep when closing the lid.

Does anyone else face this issue?

Re: /proc/acpi/button/lid/LID/state sends application to D state...

I have noticed there is a oops message.

It may have something to do with kworker.
