Thanks Matt for the patch. I used it with 8.0RC3 release. I installed FreeBSD under Linux (KVM) my 3x500GB drives were mounted as a scsi drives. Installation went smoothly but when I rebooted FreeBSD guest it hang as usual ;) with "ZFS: i/o error - all block copies unavailable", well it also spit out some LBA errors for the first time. I was a little disappointed, because I've been trying for three weeks to replace my Debian system with broken ext3 fs with FreeBSD on raidz. But I thought to myself I'll give it a try, and run FreeBSD native. To my suprise it welcomed me with login prompt. Once again thanks for the patch. It would be good idea to merge it with final release.
