Martin, I have the same problem on my Sony Vaio C1VE,
Intel Corp. 82371AB/EB/MB PIIX4 IDE (rev 01), HITACHI_DK23AA-12 disk.

It doesn't even boot, the "DMA in progress error..." appears just
after having mounted the root partition. 2.5.23 worked on this laptop.

I've added, as you suggested the following patch:

===== drivers/ide/ide.c 1.110 vs edited =====

                 drive->sleep = 0;
 
                 if (test_bit(IDE_DMA, ch->active)) {
- printk(KERN_ERR "%s: error: DMA in progress...\n", drive->name);
+ printk(KERN_ERR "%s: error: DMA in progress...%p\n", drive->name, ch->handler);
                         break;
                 }

And the bad news is that ch->handler is NULL...

Stelian.
