[gentoo-user] kernel 2.6.14.2 and problem with ACPI (lost interrupt)

[gentoo-user] kernel 2.6.14.2 and problem with ACPI (lost interrupt)

[pat]

Hi,

I've decided to switch to new kernel. When I've rebooted the system
start to type error messages and newver stoped.

The message is:
hdc: lost interrupt
irq 15: nobody cared (try booting with the "irqpool" option)

I found the problem is ACPI, but I don't want to turn off the ACPI support.

The configuration works fine for 2.6.11.11 kernel.

Please, could someone help me ???

Thanks

	Pat

Have you tried booting with the 'irqpool' kernel option as suggested
by the error message?

Have you tried booting with the irqpool option as the messages say 
(whatever the "irqpool" option is)?

Yes, I did. But I've made a mistake, the option is irqpoll not irqpool :-\ So
I'm sorry about this. With this option there's only once the error message and
the system boots. But I want to ask if someone knows why this happen, I want
to use swsuspend and ACPI and finally I don't want to lose data.

Thanks for help.

I can't see why something should happen to your data (unless you throw 
your computer out of the window in anger and frustration...)

Anyway... you mean that, if you put the "irqpool" option, ACPI does not 
work?

Too expencive to throw it out of window :-)

Well, the ACPI works, and it looks like everything works. I'm googling why
this happen (an explanation), but without success :-\ I'm just curious, that's
all.

Thanks a lot for your help.

This is what I could find
"It implies the BIOS handover failed and then we get an IRQ mess."
http://lkml.org/lkml/2004/12/6/75
Could you check in your BIOS and see how many devices are sharing IRQ or how 
is your BIOS handling IRQs? May be a BIOS update is needed?
