GGATE can generate such an error in some situations (e.g. queue is full). Please, increase debug level to 1 (kern.geom.gate.debug=1) and send me debug printfs from before panic. We can see other serious problem here - UFS cannot handle EIOs properly... -- Pawel Jakub Dawidek http://www.wheel.pl pjd@FreeBSD.org http://www.FreeBSD.org FreeBSD committer Am I Evil? Yes, I Am!
