Description Richard W.M. Jones 2011-05-10 14:49:25 UTC
Description of problem:

This seems to be the same as this Ubuntu bug:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/765082

With all up to date Fedora 15, ips-monitor kernel thread is
constantly in D state, resulting in the load avg always being
over 1.0, resulting in the laptop fan running continuously.

Version-Release number of selected component (if applicable):

Linux spin.home.annexia.org 2.6.38.5-22.fc15.x86_64 #1 SMP Mon May 2 19:28:55 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux

How reproducible:

Always.

Steps to Reproduce:
1. Nothing, just boot the machine.
2.
3.

Additional info:

$ ps ax | grep ' D '
  723 ?        D      0:04 [ips-monitor]
 3477 pts/0    S+     0:00 grep --color=auto  D

probably worth a commonbugs note; do we know what systems this will affect?

I've installed the update but not booted to test it yet.

Mine is a Thinkpad T510W.

I'm not sure this is common .. I seem to be the only one
that has noticed :-)

Intel systems with integrated i915 graphics.
IPS controls power sharing between the CPU and the GPU.

I can confirm this fixes it for me.  Load is down to near 0, and ips-monitor is no longer in D state.
