Hi,
2 days ago I proposed a patch which fixes the crash you reported in ticket #141. Although you confirmed the patch solves the issue I haven't pushed it yet as the cause seems to be a bug within the Intel driver and should be fixed there (unless we do something horribly wrong). Could you please let us know the driver version that was used in your test setup ? A 'modinfo iwlagn | grep version' should do. We will then get in touch with the Intel wifi maintainers.
Regards, Marek
