Fwd: [Daniel Shahaf: Re: zroot won't mount after 9.0-RC2 -> 9.0-RELEASE upgrade]

[Daniel Shahaf]

Forwarding to fs@ per a colleague's suggestion.

tldr: amd64 host running 9.0-RC2 with zfs root won't boot 9.0-RELEASE's
self-compiled GENERIC kernel, hanging at mountfrom>.  Details below.

The previous thread is here:

Thanks.
