I have the same problem with the LBA stuff etc: http://lists.freebsd.org/pipermail/freebsd-current/2009-May/007450.html I was using the current sources at the date I posted though, and not the older snapshot (which, at least at the time, didn't have RAIDZ boot support). I never got to mounting any root FS, though, it never let me load the kernel. Regards, Thomas PS. Nice pool name. ;)
