this looks like a bios bug in the mptable...
Although the customer had reported this bug as (very!) important,
neither he nor we were able to reproduce the problem. Systems which
have shown this problem have been replaced and the customer is now
satisfied and has released the systems for productive work. We now
assume that this was an intermittent board fault caused by defective
components or problems during the manufacturing process, not a serial
Please close this bug.
...or maybe a firmware bug fixed by the vendor.
In either case, closing as NOTABUG.
