zfs fails to import zpool after upgrade xenial alpha2

[Zach Villers]

installed xenial alpha 2 yesterday, ran sudo apt-cache update && sudo apt-get dist-upgrade today. I didn't follow all of the messages, but it seemed to go ok. I rebooted and could not find my zpool. I found this in /var/log/syslog;

Running modprobe -i on spl and zfs succeeds and then the zpool is found with filesystems intact and mounted.

I'm not super familiar with how dkms should work with ubuntu, but I didnt think I should have to manually load the modules after an upgrade?

can you confirm if this issue is still present in the daily images. Alpha 2 is 6 weeks old now.
