I have a xen 4.1.1 with a 3.0.4 linux kernel running on a Supermicro
Supermicro X8DTL-iF motherboard with 16GB of RAM.

If I run the 3.0.4 kernel on the bare metal dmidecode works fine. If I
run it under xen  dmidecode fails to work. On other systems with
different hardware but identical software dmidecode works correctly
under xen. On this hardware with xen 3.4.1 & linux 2.6.18, dmidecode
works correctly under xen.

The error message suggests to me that the bios data is partially
available as it gets the number of structures correct, but is corrupted
fairly early on. There are no DomUs running on the system.

I have attached a good and a bad dmidecode output log.
