"vr0: rx packet lost"

[David Ehrmann]

I'm using 7.0-RELEASE.

When there's heavy network traffic through the vr0 interface, I see lots 
of "vr0: rx packet lost" messages, and occasional "vr0: watchdog 
timeout" messages.  I googled and found some information, but it was on 
an earlier version of FreeBSD, and there weren't any solutions.  I 
didn't load vr as a module, and it's not listed by kldstat, so I assume 
it was build into the kernel.

Ideas?  Is there any additional information I should provide?
