I'm wondering if you are having the same problem I am.  Mine appears to 
fall into the debugger.  If after resume, when it's sitting there 
apparently doing nothing, if you type 'call doadump' does it look like 
it dumps to the disk?  The hard drive should run for a while, then when 
it stops, type 'reset' and let it boot back up.   Make sure you have a 
dumpdev line in your /etc/rc.conf before you do that.  If it gives you a 
core file on bootup, then some of the guys on this list will surely be 
able to help us.
