SubjectIDE, DMA, and lost interrupts.
As the subject of lost interrupts is brought up again, I feel like pitching
in again :)

Uniform Multi-Platform E-IDE driver Revision: 6.30
PIIX4: IDE controller on PCI bus 00 dev 39
PIIX4: not 100% native mode: will probe irqs later
    ide0: BM-DMA at 0xffa0-0xffa7, BIOS settings: hda:DMA, hdb:pio
    ide1: BM-DMA at 0xffa8-0xffaf, BIOS settings: hdc:DMA, hdd:pio
hda: FUJITSU MHG2102AT, ATA DISK drive
hdc: MATSHITA CR-175, ATAPI CDROM drive
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
ide1 at 0x170-0x177,0x376 on irq 15
hda: FUJITSU MHG2102AT, 9590MB w/512kB Cache, CHS=1222/255/63
hdc: ATAPI 24X CD-ROM drive, 128kB Cache
Uniform CD-ROM driver Revision: 3.06
Partition check:
 hda: hda1 hda2

If DMA is enabled in the kernel compile, the last message will instead be:

 hda: lost interrupt

and the laptop will lock up.
