I got this problem on my laptop, too. I somehow managed not to 
install the kernel during a recent update so my userland is slightly 
newer than my 11-CURRENT r292755 kernel (and also forgot to 
make proper ZFS snapshots…).

While I can build a newer kernel but when I boot i.e. r296556 
`zfs(8)' coredumps and I can't mount anything but the rootfs…
I guess I need to get kernel & userland back in sync to fix this.

I will try to build the userland matching my kernel first as
I know its revision from `uname -a`.
If anyone has a better approach or tips, please let me know.
