But backing out r229370 (only USB-related changes) fixes the hang. I am puzzled...

So it looks like I have to find firewire machine, revive attilio@'s netdump [1] code, or implement phk@'s soundcard tricks. ./danfe [1] http://lists.freebsd.org/pipermail/freebsd-current/2010-October/020405.html _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-mobile To unsubscribe, send any mail to "[email protected]"
