"It appears to work". A long time ago I bought a new PC; it run Windows, it installed Solaris (pre-ZFS) but when I tried to build on-net, something would die because of a SIGBUS or a SIGSEGV. When I finally run memtest86 (did require a BIOS which supported a USB keyboard properly), I had one broken 512MB dimm and I replaced it. Similarly, when someone upgraded and started to use ZFS he continuously got bad checksums; and in the end it turned out the powersupply was broken (not a "bad brand" but one which was broken, delivering out-spec voltages) Casper _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
