Comment 7 for bug 123617

It should be obvious from my logs, but I have 4 IDE controllers: 2 VIA-provided and 2 Promise PDC20265.

My setup is as follows:

* DVD+-RW as master (/dev/hda);
* plain CD-ROM as master (/dev/hdc);
* my main hard disk as master (/dev/hde).

The problem happens when the hard disk is accessed: without passing irqpoll to the kernel, I can't actually boot (well, I *can* boot, but I receive a lot of messages regarding DMA being disabled).

Anyway, the dmesg attached earlier shows that I have a "irq 10 nobody cared" problem. I used to have this with kernel.org kernels, but only when I used another hard drive (as /dev/hdg). Now, it's showing up here with ubuntu's kernel much earlier... :-(

Anyway, please let me know if I can help this further.

Regards, Rog'erio Brito.
