zfs mirror root install - panic

[Anton Shterenlikht]

I was trying to install 10.0 release, from a CD, on sunblade 1500
with 2x80GB ide disks.
I followed
https://wiki.freebsd.org/RootOnZFS/VTOC8ZFSBoot/9.x-RELEASE

but when I got to installing the OS, I got panic
at the kernel.txz stage. The latest progress was
40% and 97% overall.

Anybody has done this successfully?

I'm going to try the 9.x installation CD in the meantime.
