Description of problem: The /var/log/messages file is continually spammed with the message below. kernel: phy0 -> rt2500pci_set_device_state: Error - Device failed to enter state 1 (-16) Version-Release number of selected component (if applicable): 2.6.33-149 How reproducible: Use a rt2x00pci chipset wireless lan card that does not support powersaving Steps to Reproduce: 1. Install a wireless lan card with chipset using rt2x00pci 2. Configure wireless lan 3. Watch /var/log/messages Actual results: kernel: phy0 -> rt2500pci_set_device_state: Error - Device failed to enter state 1 (-16) Expected results: no such messages Additional info: Workaround is to as root run the command 'iwconfig wlan0 power off' rpm -q kernel kernel-2.6.33.3-85.fc13.i686 kernel-2.6.33.6-147.2.4.fc13.i686 kernel-2.6.33.8-149.fc13.i686 [root@... ~]# yum info kernel Loaded plugins: keys, presto, refresh-packagekit, rhnplugin, rpm-warm-cache, : upgrade-helper This system is not registered with RHN.

There is no functional problem, only logs are messed up right? If so I could only modify the code to not print massage if device not support power save to fix problem.
I don't know if there is not a functional problem. What I did was to add the following lines to rc.local # configure rt2500pci power mgmt -> off iwconfig wlan0 power off This had the effect of disabling the attempt to set the card into power-save mode. This for me is the preferred solution. Since I do not know if the performance of the card is hindered by the continual attempts to set power-saving mode. If there is a way to interrogate the card, at initialisation, to see if it supports power-saving mode and then act accordingly that would be the preferred solution.
We have a bit similar problem reported upstream. http://marc.info/?l=linux-wireless&m=126997977510309&w=2 We have upstream fix for it, not in 2.6.33 nor 2.6.34 kernel. commit 9655a6ec19ca656af246fb80817aa337892aefbf Author: Gertjan van Wingerde <gwingerde> Date: Thu May 13 21:16:03 2010 +0200 rt2x00: Fix failed SLEEP->AWAKE and AWAKE->SLEEP transitions. Maybe above commit helps with that issue too. Can you test this patch or boot updated kernel (for example run F-14 or rawhide liveCD) ?
I have run this on the Fedora 14 Alpha Live DVD and configured the wireless card. I observed no messages on device failure being written to the log. So it looks like the problem is not in F14.
We could apply commit from comment 3 to F-13, but there is no certain that it fix the issue and we have easy workaround, so I'm closing bug with NEXTRELEASE.
I backorted fix from comment 3 and some different rt2500 fix because other user report a kernel crash caused by these problem (Bug 642031). Fixes are now included in kernel-2.6.34.7-62.fc13 .
