Ubuntu 10.10 stock kernel (2.6.35-22-generic) crashes in compat_flush_scheduled_work(), that is called e.g. when mac80211 module is unloaded. The problem was introduced with 80bf8a83 compat: backport system work queues system_wq and system_long_wq The crash happens in compat_flush_scheduled_work() where both flush_workqueue() and flush_scheduled_work() are called successively. Removing one of them resolves the issue. All compat-wireless tarballs after 2012-03-18 are affected.
