Bug Description

I am running Linux Mint 10 Julia (Gnome 32-bit), kernel version 2.6.35-23-generic (i686). I have an Atheros AR9285 wifi adapter, which is using the standard ath9k driver.

After I create a new adhoc network, everything is fine for a while, but eventually the computer freezes and the screen goes blank. This happens consistently on my machine. If I don't create an adhoc network, it will keep running with no problem, but if I create and stay connected to the adhoc, it will eventually crash.

I looked in the Log Viewer and noticed the following reports:

Dec 18 15:17:49 eeebox kernel: [ 3783.008027] wlan0: No active IBSS STAs - trying to scan for other IBSS networks with same SSID (merge)

Hi James,

Please be sure to confirm this issue exists with the latest development release of Ubuntu. ISO CD images are available from http://cdimage.ubuntu.com/daily/current/ . If the issue remains, please 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 694115

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.
