No, nothing to do with my hardware because, until the date I mentioned, 
the UDMA was correctly set for both IDE lines. It changed on 1 April 
which is when there were upgrades including something to do with kernel 
firmware.

I am glad to see that SATA devices are not not affected.

However, "SATA uses the same basic ATA and ATAPI command-set as legacy 
ATA devices." which makes me wonder if what you just stated is 
absolutely correct.
