First of all, Matthias-Christian, thank you very much for your kind answer. I have already tried contacting the linux-ide mailing list as a CC to my earlier messages, but I got no response. I am including some details in this e-mail. I included Bartlomiej in the CC, as he is listed as general IDE maintainer in the MAINTAINERS file. > Report it to http://bugzilla.kernel.org/. Maybe you'll get help there. Thanks. I will try filing a bug on that system as soon as I get the reply to create my account there.

In my case, my problem is not with irq 5, but with irq 10, as I mentioned earlier. The situation is this: I have an Asus A7V motherboard with 2 VIA vt82c686a controllers and 2 Promise PDC20265 controllers. I recently bought myself a new DVD recorder and since Alan Cox told me[*] that the Promise controllers had problems with ATAPI devices, I decided to arrange my system this way: /dev/hda: the DVD recorder (VIA controller, master) /dev/hdc: an old CD recorder (VIA controller, master) /dev/hde: my first HD (Promise controller, master) /dev/hdg: my second HD (Promise controller, master) The Promise controller is able to control the HDs (which now have exclusive 80-pin cables) at their maximum, but I get the following stack trace if I have /dev/hdg turned on: - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - ACPI: PCI interrupt 0000:00:11.0[A] -> GSI 10 (level, low) -> IRQ 10 PDC20265: chipset revision 2 PDC20265: 100% native mode on irq 10 PDC20265: (U)DMA Burst Bit ENABLED Primary PCI Mode Secondary PCI Mode. ide2: BM-DMA at 0x7400-0x7407, BIOS settings: hde:pio, hdf:pio ide3: BM-DMA at 0x7408-0x740f, BIOS settings: hdg:pio, hdh:pio Probing IDE interface ide2... hde: QUANTUM FIREBALL CX13.0A, ATA DISK drive ide2 at 0x8800-0x8807,0x8402 on irq 10 Probing IDE interface ide3... hdg: QUANTUM FIREBALLlct15 30, ATA DISK drive irq 10: nobody cared!

I can provide much more details if I know what is relevant. I had already posted some old dmesg logs at my site , but this was before I got myself a second 80-ribbon cable (I expected that the problem would go away, but it didn't). Any other comments are more than welcome. Thanks in advance, Rog?rio Brito.
