Interesting. When you do the import, try doing this:
zpool import -o ro yourpool
And see if that fares any better. If it works, could you send the
output of "zpool status -v"? Also, how big is the pool in question?
Either access to the machine, or a way to copy the crash dump would be
useful. I can give you more commands to run at that point.
