problems with cdrom (IRQ ?)

[Alessandro Ghigi <ghigi@math.mit.edu>]

Booting  Potato on my laptop (Dell Latitude) I receive the following
message


hda: FUJITSU MHH2064AT, ATA DISK drive
hdc: IRQ probe failed (0)
hdc: IRQ probe failed (0)
hdc: ATAPI cdrom (?)
hdd: IRQ probe failed (0)
hdd: IRQ probe failed (0)
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
ide1 at 0x170-0x177,0x376 on irq 15
hda: FUJITSU MHH2064AT, 6194MB w/512kB Cache, CHS=789/255/63, UDMA
hdc: ATAPI 24X CD-ROM drive, 128kB Cache


This has no catastrophic effects, but nonetheless I would like to
understand what is the problem.

Thank you
Alessandro
