There are a few reports of this on the freebsd-stable mailing list in  
March and I'm also experiencing the same problem, so far none of the  
suggested resolutions has helped for me.
http://lists.freebsd.org/pipermail/freebsd-stable/2008-March/thread.html

I've got the issue on a custom built box with amd64 + 7.0 + gmirror  
and I've got a Proliant ML110 G5 running 6.3 I'd like to upgrade to  
7.0 but too scared to do so until this issue appears to have been  
identified and fixed.
Copying in freebsd-stable as it's not just a problem on Proliant.
