The assertion I added some time ago is too strong in case of gjournal. Gjournal can modify bio_caller1 for in-flight bios from another thread, and the assertion doesn't and can't really take that into an account. The assertion should be removed, pity, because it's still useful for other GEOM classes. To make your system usable, remove DIAGNOSTIC from your kernel configuration. -- Pawel Jakub Dawidek http://www.wheel.pl pjd@FreeBSD.org http://www.FreeBSD.org FreeBSD committer Am I Evil? Yes, I Am!
