IWLAGN 4965abg MAC is in deep sleep

Thank you for taking the time to report this bug and helping to make Ubuntu better. This bug did not have a package associated with it, which is important for ensuring that it gets looked at by the proper developers. You can learn more about finding the right package at https://wiki.ubuntu.com/Bugs/FindRightPackage. I have classified this bug as a bug in linux.

When reporting bugs in the future please use apport, either via the appropriate application's "Help -> Report a Problem" menu or using 'ubuntu-bug' and the name of the package affected. You can learn more about this functionality at https://wiki.ubuntu.com/ReportingBugs.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please execute the following command, as it will automatically gather debugging information, in a terminal:

apport-collect 463316

This will help us to find and resolve the problem. Bear in mind that you may need to install the python-launchpadlib package from the universe repository. Additionally, when prompted to give apport-collect permissions for Launchpad you will need to give it at least the ability to "Change Non-Private" data as it will be adding information to your bug report. Thanks in advance!

Is this related to 7d930bc33653d5592dc386a76a38f39c2e962344? Apparently there were reports of problems after deauthenticating that were fixed by reverting that commit.

Whether it's related to that commit or not, I'm seeing a very similar problem with 2.6.31-15-generic. It seems to start after the following in dmesg:
[18363.512539] No probe response from AP 00:17:31:ae:21:6f after 500ms, disconnecting.
[18364.152558] iwlagn 0000:07:00.0: Error sending REPLY_RXON: time out after 500ms.
[18364.152570] iwlagn 0000:07:00.0: Error setting new RXON (-110)
[18364.653817] iwlagn 0000:07:00.0: Error sending REPLY_SCAN_CMD: time out after 500ms.

After a number of similar messages, it eventually starts spitting out
[36369.096452] iwlagn 0000:07:00.0: MAC is in deep sleep!. CSR_GP_CNTRL = 0xFFFFFFFF

Hi!
Can you try this solution:

Add pci=use_crs at the end of the line

linux /boot/vmlinuz-2.6.31-19-generic root=UUID=8a7ca0ae-ec6e-4df9-9661-edccf300d223 ro quiet splash

in the file /boot/grub/grub.cfg and reboot

@superlex: So does this mean that this problem arises because of incorrect or failure in allocation of PCI resources?

I shall give your solution a shot. The problem comes up very randomly so even a weeks worth of testing would not be enough to know for sure in my case. Is there anything in the log files that will tell me if the fix is working?

Thanks for the help!

The best way to know if it works is waiting and seeing what happens.
According to me, messages in dmesg are important only when the problem occurs.

I do not know if the solution is correct, that's why I'm trying and I ask you to try too.
Until now I had no more problems.

Sorry for the delay, but I'm in holiday (ops) and I'll be back with my
notebook next week. I'll try to apply the suggested parameter
immediately and to send all the feedback.

Thanks' for the support. Frank.

Hi,
another time, sorry for the delay. No, nothing change adding the
parameters. The only VERY strange behavior is that, for the first time,
I saw the WiFI green light on, when I restart the PC from the login
display. Really strange and after two times I was no longer able to
replicate the behavior.
The only I did was to use the iwconfig command "iwconfig wlan1 txpower
15" that usually is 0.

Now I'm using the 2.6.31-21 kernel and the compat-wireless-2010-03-19.
Ubunt backport is unusable: MAC in deep sleep.

Thanks' Frank

Hi Francesco,

If you could also please test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.
