Bug Description

Hi,

I'm using a RaLink RT2561/RT61 802.11g PCI WLAN card in my computer running Ubuntu 8.10.

WLAN works fine if I boot normal, but if I resume from suspend or hibernate there is no WLAN. The only way to get it back up is to reboot the computer which makes suspend and hibernate useless.

I have uploaded my hardware information to launchpad but I don't know where I can find it (I stated my username at launchpad).

Please run the command "sudo lspci -vvnn > lspci-vvnn.log" and attach the resulting file "lspci-vvnn.log" to this bug report. This will provide the hardware information.

Please run the command "dmesg > dmesg.log" after resuming and attach the resulting file "dmesg.log" to this bug report. This will provide the kernel messages made while resuming.

Thank you for taking the time to report this bug and helping to make Ubuntu better. :-)

I'm going to mark this bug as 'incomplete' which means that it needs some more informations from you.

Hi Florian,

thanks for your reply.

Requested information attached.

Do you know if there is a solution or workaround already?

You can try the workaround from https://bugs.launchpad.net/ubuntu/+source/linux/+bug/300792/comments/13

You dmesg.log seems to be created after a normal boot. Could you please add one that is created after resuming? Thank you!

Hi Florian,

the workaround worked for me, thanks!

I've attached the dmesg.log after resuming (yet without the workaround).

Hi Florian,

unfortunately the workaround made the situation even worse.

If I resume from suspend, Ubuntu tries to connect to the WLAN: One of the two bubbles is green, the other one is gray and the animation is rolling. If I click on the WLAN icon, the whole computer freezes and I have to reset it.

Have you ever seen this behavior?

Hi,

why is this bugreport on incomplete? What information is missing?

I'm still facing this issue which is serious, because the system won't properly shut down (data loss).

Sorry, this bug just went out of my sight. Thanks for sending a reminder.

Could you please add a dmesg.log and /var/log/pm-suspend.log after resume with the workaround?

Frank Niedermann (fbn) wrote :

sure, attached!

Hi Florian,

have you received the two files? Anything else I can provide to help solve this issue?

Thank you! Since this bug has enough information provided for a developer to begin work, I'm going to mark it as confirmed and let them handle it from here. Thanks for taking the time to make Ubuntu better!

I get this same problem. Attached are lspci-vvnn.log and dmesg.log, both created after resuming from hibernation when wifi is not working. wifi works fine from a clean boot.

Hi,

is there a way to see when a developer picks this bug?

The same problem here with Kubuntu 8.10.
Suspend to Ram works quite fast (even faster than with 8.04), but after restart network-manager isn't able to connect to my wlan any longer.

Additionally kde warns about a problem with kbluetoothd and the bluetooth icon in the control bar disapears.

Attached you find an excerpt of my syslog beginning right before suspending the machine and ending after network-managers failed attempt to connect to my wlan.

Thank you guys for developing ubuntu! It's my favourite distro and I assume kde4 will be great when the current quirks are gone. For now I will probably switch back to 8.04, but I'm looking forward to Jaunty.

Second attachment is tho output of sudo lspci -vvnn > lspci-vvnn.log

Hi Frank,

Care to test and confirm if this issue remains with the most recent pre-release of Jaunty 9.04 (currently Alpha4) - http://cdimage.ubuntu.com/releases/jaunty/ . It contains a newer 2.6.28 based kernel. You should be able to test suspend (not hibernate) via a LiveCD. Please let us know your results.

It seems there are a few reports about issues with the rt61pci driver after a suspend/resume cycle. I'm going to mark this as a duplicate of bug 294058 so that the developers only have a single bug to track. Please continue to track this issue at that report. Thanks.
