>Description:
I have a ZFS pool version 5000, made from a mirror of 2 disk partitions, which I typically use under Linux with ZFS on Linux.

A few days ago, my Linux machine hanged while resilvering the pool, and since, it will not mount under Linux anymore, causing the Linux SPL module to crash.

So I tried and see if I could rescue this pool using the latest FreeBSD available.

Unfortunately, trying to mount this pool with FreeBSD causes FreeBSD kernel to crash as badly as Linux does.

A screenshot of the kernel crash message is available here : 

https://www.dropbox.com/s/f2jtg864jzut6o5/P1030508.JPG

I have a 1 TB ZFS pool with precious data on it that looks irremediably lost, so you can imagine to which point any help will be highly appreciated...

TIA.
