Sorry for noise,
I was playing with ZFS on this usb stick and created zfs:builder pool
on GPT partition.
Then I created bootable instalation disk on this usb stick, but didn't
properly destroyed zfs:builder pool.
I tried to install BETA2 but got this panic.
I plugged stick in another box, run zpool import and there was
zfs:builder pool, faulty. I could not import it.
I zeroed usb stick, created fresh installation image and no more panics.
Lesson learned: always clean-up after yourself! :)
I'll beter rewrite this script to s/dd/gpart delete/

Everything should be made as simple as possible, but not simpler.
