If so, we have fix on wireless-testing tree: http://git.kernel.org/?p=linux/kernel/git/linville/wireless-testing.git;a=commitdiff;h=543cc38c8fe86deba4169977c61eb88491036837 Otherwise perhaps you could photo crash logs on virtual terminal (switched by Alt+Ctrl+F2 from X-window) or by using netconsole or kdump.
