I've had this error for as long as I've had Linux installed and have needed to boot using a live cd. I've tried Mepis as well.

irq 3:nobody cared!
handlers:
[] (ide_intr+0x0/0x190)
disabling IRQ #3

It wouldn't be a problem if I didn't need to access my secondary scsi drive, which is where Linux is installed. My sata drive relies on a sata controller host card, which is most likely where the problem lies. When I unplug the sata cable, Mepis boots without a hitch. My primary (Windows) drive is ide.

Thanks for any help. It would be nice to finally resolve this.
