We have a few R710's running FreeBSD 8.0-RELEASE and they have been 
running great.  However, they all have the PERC6/i; we don't have any 
with the H700 controller.

You can try rebuilding your kernel with the patch I have attached.  It 
will make the "Copy out failed" messages a bit more descriptive.  
Additionally, you may want to include the kernel option "KDB" which will 
enter the debugger on panic (instead of rebooting).  From here you'll 
want to type 'bt' to get a backtrace.
