I'm really sorry, but I realized that I had not rebuilt initrd when I'd
installed a new kernel with the patch applied. So I did that and I can confirm
that I no longer got OOPS but those DMA turn offs were back instead as they
used to happen with <= 2.6.28 kernels:

[  663.442788] hdd: cdrom_decode_status: status=0x51 { DriveReady SeekComplete
Error }
[  663.445040] hdd: cdrom_decode_status: error=0x40 <3>{ LastFailedSense=0x04 }
[  663.446768] ide: failed opcode was: unknown
[  663.454549] hdd: cdrom_decode_status: status=0x51 { DriveReady SeekComplete
Error }
[  663.456681] hdd: cdrom_decode_status: error=0x40 <3>{ LastFailedSense=0x04 }
[  663.458541] ide: failed opcode was: unknown
[  663.464783] hdd: cdrom_decode_status: status=0x51 { DriveReady SeekComplete
Error }
[  663.466847] hdd: cdrom_decode_status: error=0x40 <3>{ LastFailedSense=0x04 }
[  663.468764] ide: failed opcode was: unknown
[  663.473414] hdd: cdrom_decode_status: status=0x51 { DriveReady SeekComplete
Error }
[  663.475365] hdd: cdrom_decode_status: error=0x40 <3>{ LastFailedSense=0x04 }
[  663.477259] ide: failed opcode was: unknown
[  663.477406] hdd: DMA disabled
[  663.520043] hdd: ATAPI reset complete

So yes, I can confirm that the patch fixes the OOPS with 2.6.30-rc5 and
2.6.30-rc6-git5. I'm looking forward to seeing the patch included in 2.6.30-rc7
and 2.6.29.x, it looks pretty important to me.

What is more, I "played" a bit with IDE cabling and switched my CD/DVD drive to
IDE master and I could not even reproduce the errors above (and hence annoying
DMA turn off is gone too) any more. So it is good news on all fronts for me.

I leave it for you to close the bug but it is fully RESOLVED as far as I'm
concerned.
