I guess I'm seeing this problem. I'm trying to get my P4P800 motherboard with
an ICH5 chipset working completely. So far I've been living without the cdrom
or DVD players. I see lots of other posts on linux-kernel about the same
problems:
Whenever I try to access the cdrom my system becomes unusable. Due to high
interrupts, typically over 150k/s. I thought libata would help, but I don't
understand how to use the PATA drive and the cdrom drives while I'm using it.
The situation is that I have two SATA drives, a PATA drive and two cdrom
drives (actually one CD burner and one DVD drive). They are
Primary Master: PATA Drive
Secondary Master: CD Burner
Secondary Slave: DVD-Rom
SATA-1: SATA Drive
SATA-2: SATA Drive
I've tried 2.4.23pre4 (no libata), 2.6.1 (IDE drivers), and 2.6.1 (with scsi
libata drivers) with the following results:
2.4.23pre4: as soon as the cdrom is touched I see bursts of 150k interrupts
per second and the system becomes unresponsive momentarily every few
seconds.
2.6.1 with regular IDE drivers: same as above except the system feels
responsive except for disk i/o. I see printks of "Disabling interrupt #18"
and all disk i/o freezes for a few seconds.
2.6.1 with scsi ata_piix driver: the SATA drives show up and work fine but the
PATA drive and the cdroms doesn't show up at all. This is true even when I
compile with the CONFIG_IDE, CONFIG_BLK_DEV_IDE, and CONFIG_BLK_DEV_IDECD
enabled.

I have intel D865PERL, three IDE HDs, one CD burner, one SATA disk,
using scsi ata, kernel 2.4.21-ac4 with libata5 patches (libata patches
needed beacause SATA driver is over 133GB), seems to be working fine, I
am not using CD burner very often but I didn't see any instability when
I used it (read or burn CDs).
When I use cdparanoia to rip audio CDs the system is quite slow but
that was always the case (even with different MB, no SATA, different
kernels etc.)
Using SATA disk as IDE disk caused the system to freeze during boot
(right after the HDs were detected)

One possible workaround it to enable both PATA and SATA drivers (using
libata) and pass "ide2=noprobe ide3=noprobe" to kernel at boot.

I have a ABIT IC7-G motherboard with the ICH5 chipset.
No reported problems with it. I would be happy to do some tests, just in
case I have not actually noticed the problems.
hda=DVD-ROM
hdb=DVD writer
hdc=SATA Seagate Hard Disc 160 Gig.
hdd=Empty.
I do sometimes have problems during BIOS startup, with it not detecting
the SATA hard disc, but pressing the reset button a few times fixes that.

I have pretty much the same setup he recommends in UPDATE except of
the "ide2=noprobe ide3=noprobe" kernel boot options, not sure why would
that be needed but my system (interl D865PERL, cd burner, ide and sata
disks) works OK without it.

Tried it on top of 2.4.25-pre4-libata1. I set the BIOS on my
Asus P4P800 to Enhanced mode, and the kernel locked solid during
boot while trying to clean /tmp.... Setting the BIOS back to
Compatible mode allows my system to boot.

The "Update" section describes the setup which - after *weeks* of
frustrating trail-and-error - managed to get things going.
Notice the unusual BIOS setting (Enhanced Mode - SATA only) which did
the trick and enabled PATA *and* SATA.
You may want to try that if you haven't already.
The ideN=noprobe my indeed not be necessary . It was recommended by Jeff
Garzik to me at some time IIRC. Kernel 2.6 does *not* need the noprobe
stuff AFAICT.
FWIW my P4P800 Deluxe is working flawlessly with 4 P-ATA devices (2 HDs,
a ZIP100 and a 48x Burner) and one SATA 160Gb HD.
I'm using 2.4.22-bk36 with matching libata patch so i'd think that any
kernel 2.4.23+ will do the trick.

Thank you!
That was the key thing I was missing. With this setting the PATA drives show
up on /dev/hd{a,b,c,d} and the SATA drives show up on /dev/sd{a,b} (using
ata_piix). And everything seems to work pretty well in 2.6.1.
I've only tried the PATA hard drive and reading from cdrom. I haven't tried
burning cds or playing a dvd yet.

I have an Asus P4C800-E Deluxe, with two drivers on the ICH5 sata
controllers. It is a 3Ghz cpu using HT.
I use the normal PIIX ide drivers for the pata channels, and libata for
the sata ones. I also use the vector based interrupts. Kernel is
2.6.1-bk4.
Anyhow, I do not think the interrupt count is _that_ high, as it shares
with usb and network and I cannot complain of problems with cdrom, etc,
but I decided to try the patch anyhow. It have some interesting results
though. First, network stops responding after a few minutes of uptime
(especially easy to reproduce if you have heavy network traffic), then
for some reason you cannot start a new program/login/etc, but those
running seems Ok, and lastly X becomes totally unresponsive (although
alt-sysrq-b still do work).
