Default Bug#496111: linux-image-2.6.26-1-amd64: iwl-wifi dumps stacks

Package: linux-image-2.6.26-1-amd64
Version: 2.6.26-2
Severity: normal

With the latest kernels, my wifi card somehow floods the kern.log with
backtraces. Though I've seen no problems with the network whatsoever.
It's just that it floods quite a lot (I've put here a short excerpt).
