Just a me too.

Everything was working great with zfsboot from 8.2-RELEASE + a patch
(http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/153552).

As I update to 8.2-STABLE after v28 MFC, I have to write a new zfsboot 
to be allowed to upgrade my pool. I get the "Read Error" after that.

PS - same comfig, a netboot with windows7 on first partition - so I 
can't switch to gpt.
