Bjorn,

I complained to Supermicro and mentioned that the beta BIOS they 
provided to one of the customers in the Redhat Bugzilla threads did not 
solve the issue at all. I also included links to both Bugzilla threads 
as well as a link to the mail you sent back to me as snipped above which 
contained your excellent analysis of the problem.

The patch applied, booted, ran, and solved the problem perfectly. Do you 
want any output or configuration files to verify anything? Let me know 
if there is anything I can do to help. Other than that if you think it 
is safe to apply this, I am in favor of adding it to the mainline or 
other appropriate tree.
