Maybe I was wrong when I called this regression, but this was very surprising behavior for me. And in 5.X I did a lot of udf debugging/experimenting and never encountered such a problem. Maybe I always did kldload before mount, I can't tell now. Anyway, this seems like an annoyance at the very least, pinning a kernel module without any important reasons. -- Andriy Gapon _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
