Default Bug#583643: linux-image-2.6.34-1-686: iwlagn disassociate under high load

Package: linux-2.6
Version: 2.6.34-1~experimental.1
Severity: normal

Dear Maintainers,

after upgrading to kernel 2.6.34-1~experimental.1 my iwlagn based
wirless lan gets unstable under higher/heavy load:

In my accesspoint (cisco 1131ag) logfile I can see:

With kernel linux-image-2.6.32-5-686 the wlan works prefectly.

Default Bug#583643: linux-image-2.6.34-1-686: iwlagn disassociate under high load

I'm not be able reproducing this bug anymore. No disassociation
after many hours with a saturated wireless link. No clue what
kind of cosmic EM-burst caused this odd problem. You can close the
bug. Sorry for the noise.

Regards
Friedemann
