So, if you don't add the 'irqpoll' option, IO to disks don't work at all
after nobody cared message, right?

IO to disks don't work for SOME disks, but some others are still Ok (I've
three SATA and two IDE).

Also, what is weird is the content of dmesg : after the nobody care, it looks
as if IRQ 23 is reuse for another device (SMBus), but /proc/interrupts still
reports it being used by libata.

I've been trying 2.6.23-rc5, and I'm still having this IRQ 23 nobody cared 
message.

Regards,
Paul

Hello,

Just to let you know that this seems to be over in 2.6.23-rc6.
Don't know exactly what fixed it, but it is no more present in my bootlog,
with or without the irqpoll option.

Nice job,
Regards,
Paul

Does this still happen with 2.6.23?  If so, please post boot log.  Thanks.

No it does not.

I have nearly the same setup (ASUS P5W-DH-Deluxe, Core2, 2GB RAM, 3
SATA and 2IDE)

And a "dmesg | grep irqpoll does not show up with results.

dmsg | grep 23 comes up with:
wifi0: Atheros 5212: mem=0xeb9f0000, irq=23

And I no longer use IRQPOLL (I dropped it somwhere between 2.6.22.?
and 2.6.23) as Kernel option.
kernel (hd0,0)/vmlinuz root=/dev/sda3 video=nvidiafb:1280x1024-32@85,mtrr,ywrap

All SATA Ports are working (except the the PMP... it "works" but I
would not recomment usign it right now because of these bugs:
http://bugzilla.kernel.org/show_bug.cgi?id=9010
http://bugzilla.kernel.org/show_bug.cgi?id=9010

Built and booted already twice, and so far, no problem anymore.
I'll continue to watch this carefully, and will report any problem that could
be related to this.
