Problem 1:
while booting the message "hdb: cdrom_pc_intr: The drive appears
confused (ireason = 0x01)" repeats several times and the system hangs
for some seconds. After booting sometimes I get the same message and
linux hangs.

Problem 2:
syslog message "irq 18: nobody cared!" followed by a call trace repeats
while booting and while running linux.

On the bottom of this mail you'll find an extract of /var/log/syslog
showing this error.


My system is a P4 630 with em64t, ASUS P5GD2 Premium board (ICH6
chipset) and nvidia 6600GT PCIe graphic card.
I'm running a self compiled kernel 2.6.12rc4 but I've had these bugs in
 self compiled kernel 2.6.11.8 and default debian kernel
2.6.11-9-em64t-p4-smp too.
The default debian kernel 2.6.8-11-em64t-p4-smp seems to be the only one
where problem 1 does not occur but problem 2 does.

Hi Alexander,
To me, it looks like both IDE channels get wrong IRQ. Didn't you
verified previously that when you go without IDE the system boots up OK?
They get some interrupts because when IRQ 201 occurs triggered by USB,
the handler for ide runs also, since it is shared with both ide and
uhci. (Can you also attach output for "cat /proc/interrupts" please).

I was going to put some code together for you over the weekend, but got
caught up in other things, sorry. The idea was to forcibly assign IRQ 14
for ide0 and IRQ 15 for ide1 in the ide driver, setup-pci.c (just for
diagnostics and proof of concept so to speak) and see if devices become
sane.
I will try tweaking it tonight. I need to make sure it works on my
system first and if it does I will send you the code. 
Thanks,
--Natalie

We did a few experiments with assigning IRQ 14 and 15, and didn't get
anywhere. 
Then I asked Alexander for the MP routing table, and it became clear
that 14 and 15 are not wired on his system. 
Below is some information that we collected.
I am showing here the case when Alexander booted with acpi=off and no
MSI, to simplify the picture.
The interrupt routing according to MPS:

this data...
