Zpool scrubs come up clean and I never see any errors reported. I've been running this hardware for 2 years and v28 for quite some time. It doesn't seem like it started happening until I upgraded to a build past RC1. I don't know where to find RC1 media and I don't know the svn revision of RC1 so I haven't tried.

The kernel backtrace you provided indicates a problem in pf(4), not ZFS.
What piece am I missing?
