I've seen reports of a recent Seagate firmware update
bricking drives again.
What's the output of 'zpool import' from the LiveCD?
It sounds like
ore than 1 drive is dropping off.

1.) Here's a similar report from last summer from someone running ZFS on
FreeBSD. No resolution there either:
raidz vdev marked faulted with only one faulted disk
http://kerneltrap.org/index.php?q=mailarchive/freebsd-fs/2008/6/15/2132754
2.) This old thread from Dec 2007 for a different raidz1 problem, titled
'Faulted raidz1 shows the same device twice' suggests trying these
commands (see the link for the context they were run under):
http://www.mail-archive.com/zfs-discuss@opensolaris.org/msg13214.html
# zdb -l /dev/dsk/c18t0d0
# zpool export external
# zpool import external
# zpool clear external
# zpool scrub external
# zpool clear external
3.) Do you have ECC RAM? Have you verified that your memory, cpu, and
motherboard are reliable?
4.) 'Bad exchange descriptor' is mentioned very sparingly across the
net, mostly in system error tables. Also here:
http://opensolaris.org/jive/thread.jspa?threadID=88486&tstart=165
5.) More raidz setup caveats, at least on MacOS:
