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 . |
