I striped two 200GB HDD to a 400GB HDD (hardware RAID). 
The partition table claims that there is a 400GB HDD, but LINUX assumes 
two separate 200GB HDD's

I replaced the first HDD by a different HDD, turned RAID off and booted 
without libata.dma=1,  and the problem occured again. 

Then, I booted using libata.dma=1, and the problem disappeared!!!

A thousand thanks to Alan Cox!!!!

If some developer is interested, then I can provide more information and 
make some more experiments. 

Best regards,  Daniel
