I'm pretty sure it's not related with my changes.

If you think vr(4) is culprit for the issue try overhauled vr(4).
I think I've fixed many unresolved vr(4) issues but it needs more
testing.
You can download the overhauled vr(4) at the following URL.
http://people.freebsd.org/~yongari/vr/if_vr.c
http://people.freebsd.org/~yongari/vr/if_vrreg.h

Note, don't use the overhauled driver on your production system.
I couldn't see any issues in the driver but it may have unnoticed
bugs.
