Yeah, that is critical for tracking down something like this.
When I have finished then I'll decide if I am in the mood to spend more time in writing up a bug report - which may or may not be acted on for years for all I know
One important thing to realise about bugzilla and reporting - it is not a support system. Which means it's a two-way thing - usually reports get acted on very quickly, especially when the proper information is provided etc.
OK, after several reboots it seems that I finally "cracked" this problematic nut and I now am getting the correct reading in Control Centre/Hardware/IDE DMA Mode showing that DMA is correctly set for all my 4 IDE devices. The way to achieve this seems to be to have DMA forced to be set for ALL devices and not just the devices which show up as not being set in CC/HW/IDM. For example, in my case CC/HW/IDM was showing this: hda set hdb not set hdc set hdd set and it was getting hdb set which was the subject of the discussion in this thread for sometime now. Up this point in time, /etc/sysconfig/ide had this: DEVICES_FORCE_IDE_DMA="/dev/hdb:udma2" and this didn't work. Doing what Silviu suggested - putting 'hdparm -d1c1u1 /dev/hdb' in /etc/init.d/boot.local - also didn't work although on the first reboot after doing so it appeared that it was working. What I did (as a "stab in the dark" I must add) is alter /etc/sysconfig/ide to read: DEVICES_FORCE_IDE_DMA="/dev/hda:udma5 /dev/hdb:udma2 /dev/hdc:udma5 /dev/hdd:udma4" and now the DMA is correctly set for hdb. Just trying to force the DMA for hdb on its own did nothing but forcing it for all 4 devices did the trick (although I suspect that forcing it for both devices on the same IDE channel/cable [0] would also have done the trick but I am not going to start playing around with this idea as I've spent enough time on this hassle already. It now works and "If it ain't broke, don't fix it".)
