If a world built with the following patch > in place still behaves the same you should better contact the ZFS > maintainers though: > http://people.freebsd.org/~marius/elfxx-sparc.c.diff I kept the same cvsup from Sunday, added that patch and rebuilt world and kernel. Now 'kldload zfs' or 'zpool status' locks the machine up, no serial console, no network. It doesn't respond to breaks on the serial console. (I didn't put the alternate break sequence in). With the kernel.old from before your patch, 'kldload zfs' will work. falcon# kldload zfs ZFS NOTICE: Prefetch is disabled by default if less than 4GB of RAM is present; to enable, add "vfs.zfs.prefetch_disable=0" to /boot/loader.conf.
