Subject: 2.6.0-test2: irq 18: nobody cared...Disabling irq #18 (i875P SATA)
Date: 01 Aug 2003 16:10:24 +0200	[thread overview]
Message-ID: <1059747024.2418.8.camel@paragon.slim> (raw)

Hi,

While booting 2.6.0-test2 on my i875P based PC I get the following:

<snip>
Adding 787176k swap on /dev/hda3.  Priority:-1 extents:1
irq 18: nobody cared!

Disabling IRQ #18


IRQ 18 belongs to the SATA interface:

ide2 at 0xefe0-0xefe7,0xefae on irq 18

Funny thing is that the SATA drive is still usable while the irq
is disabled.

I also noticed that the interrupt count for IRQ 18 is still rather high
(as I mention in a previous mail):

           CPU0       CPU1
  0:     552358          0    IO-APIC-edge  timer

Any solutions?

Cheers,
