This does appear to be zfs related, can you include the version of zfs you were running. The Ubuntu PPA was recently updated to include packages for spl/zfs-0.6.2, it would be best if you could update to the latest stable and report if the issue still occurs.
This issue did happen on the latest build from the PPA included at the bottom. Please let me know if there is any other information you would like from me.

This is happening very regularly for me too. I think since the time I moved to 3.11 kernel, its been very frequent.
I'm hitting something like this consistently during heavy IO. General protection fault, then txg_sync sits in the D state. I'm not sure when the problem started as this system is usually fairly idle.
Thanks for the additional debug, it should help.
Looks the same as https://github.com/zfsonlinux/zfs/issues/470
This was a duplicate of zfsonlinux/zfs#470 which was resolved.
My system keeps locking up and I think it might be something with zfs.
After the error happens I cannot do any zpool or zfs command. Other times the load keeps increasing and network, input devices, and video stops to function.
When I do a hard reboot it will work for a while, but will lock up after a indeterminate amount of time.
Here are some log output.
