Hi Johannes, There is a kernel bugzilla report regarding rt73usb and mesh networks: https://bugzilla.kernel.org/show_bug.cgi?id=16099 The stacktrace indicates the problem is a scheduling while atomic bug, however this seems to be triggerd by mac80211 making the bss_info_changed() callback function in atomic context. But the current documentation of mac80211 implies that this callback function is allowed to sleep. Could you check the stacktrace to see if this is indeed a mac80211 bug rather then rt73usb?
