Public bug reported:
Binary package hint: hal
When I upgraded the kernel on my System76 Gazelle (basically a ASUS
Z62FP without the Microsoft tax) from 2.6.17 to 2.6.20, the hard disk
began freezing for 30 seconds every few minutes whenever the CD/DVD
drive was empty. When there is a disk in the optical drive, the freezes
occur much less often, but I'm sure there's been at least one even with
a CD in.
The relevant part of the dmesg is:

I'm filing this bug against HAL because kernel developer Tejun Heo says
HAL is poking the CD/DVD drive and confusing it, and indeed when I kill
hald the problem goes away. On the other hand, I only noticed the
problem after upgrading the kernel, and when I force the old ide_generic
driver to be used by blacklisting ata_piix, the problem also goes away,
so maybe it should be filed against the kernel package instead.
dmesg and lspci -vvx attached
