Hey, sorry my text above has some mistakes:

Here comes the text with corrected grammar:

The wlan card "TL-WN851N" (produced by TP-Link) crashes ubuntu 11.10. Sometimes the system crashes right at the login-screen, sometimes you can use the system for 20 min. till it crashes.

I changed the wlan card and now the crashes didn t occur again.

Hello ggjj11
can you please install the latest mainline kernel
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.1-rc10-oneiric/
installing on first the one with the extension all.deb, then headers and image for your architecture (i386 or amd64)
And try again with the affected device.
If you're experiencing again some crash, then remove the device and attach here, using the button below 'Add attachment or patch' the files:
/var/log/kern.log
/var/log/kern.log.old

Thanks
Fabio

Same Problem here.
Installing the mainline kernel dosent make things better...

Thank you for taking the time to file a bug report on this issue.

However, given the number of bugs that the Kernel Team receives during any development cycle it is impossible for us to review them all. Therefore, we occasionally resort to using automated bots to request further testing. This is such a request.

We have noted that there is a newer version of the development kernel than the one you last tested when this issue was found. Please test again with the newer kernel and indicate in the bug if this issue still exists or not.

If the bug still exists, change the bug status from Incomplete to Confirmed. If the bug no longer exists, change the bug status from Incomplete to Fix Released.

If you want this bot to quit automatically requesting kernel tests, add a tag named: kernel-bot-stop-nagging.

 Thank you for your help, we really do appreciate it.

ggjj11, thank you for reporting this and helping make Ubuntu better. This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please capture the oops following https://wiki.ubuntu.com/KernelTeam/KernelTeamBugPolicies#Capturing_OOPs ? As well, can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux <replace-with-bug-number>

Also, if you could 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.

Any experiences with 12.04 LTS and TP-LINK TL-WN851N?

[Peter Janeck (p-janeck)]

Yes, I have tried 12.04 and 10.10 as well as Fedora 16 and 17 beta with TP-LINK TL-WN851N. Neither of them worked. The system freezes shortly after connecting to the wlan.
