Hi Andrew,
appologies for my delay in responding. I have just mailed you the 
crashing hvmloader off-list using my main mail address. It is the debug 
version from xen-4.5.2 together with symbols (as splitdebug) using the 
non-working seabios-1.8.2 - all packed up in a compressed tar file using 
relative names and maintaining the directory structure required for 
splitdebug to work.
If you would also like me to send you the failing seabios binary 
separately, just let me know. My understanding, however, is that seabios 
is anyways emebedded in the hvmloader binary.

Attached please find the config file for one of the HVM virtual machines 
that crashes with the hmvloader binary sent to you by mail. The vm, btw, 
is running the pfsense firewall using FreeBSD. Any more information 
required - just ask.
Many thanks Atom2
