as you might have noticed, ieee80211_draintask() is a wrapper around taskqueue_drain(9). Have you had a look at taskqueue_drain(9) man page? https://www.freebsd.org/cgi/man.cgi?query=taskqueue_drain&apropos=0&sektion=0&manpath=FreeBSD+11.1-RELEASE+and+Ports&arch=default&format=html On Sun, Aug 20, 2017 at 11:48, Farhan Khan<khanzf@gmail.com> wrote: Hi all, I traced back where my driver-in-development hangs when I issue "ifconfig wlan0 up", and it hangs on ieee80211_waitfor_parent(), specifically: ieee80211_draintask(ic, &ic->ic_parent_task); Reference: http://src.illumos.org/source/xref/freebsd-head/sys/net80211/ieee80211_proto.c#1406 I am not familiar with the source just yet, What does this function do? And, what is ic_parent_task? It appears that Andriy reported this same issue here: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=208860 but I did not see a resolution.
