disabling irq, nobody cared

disabling irq, nobody cared

[Adrian Sandor]

Hello all,

Apologizes if this is a duplicate, many people seem to
have similar error messages but it may or may not be
the same problem.
For the past couple of weeks I've been trying hard to
install a distribution of linux on this computer, and
failed every time.
Suse, Fedora, Knoppix hdd installation, Gentoo... all
failed with every kernel I tried.
The ones that didn't hang or reboot immediately
displayed error messages like:

irq 18: nobody cared!
Call Trace:

Disabling IRQ #18

and

hdb: dma_timer_expiry: dma status == 0x64
hdb: DMA interrupt recovery
hdb: lost interrupt

with various irq numbers and stack traces. That either
slowed the system to a crawl or flooded the console
with "disabling irq x" messages.

I have tried different kernel options: SMP and no SMP,
disabling APIC, etc, different kernels: 2.4.25, 2.6.5,
2.6.8-rc1, even tried some patches, but nothing worked
(2.4 usually hanged, and 2.6 gave the above error
messages).
The only kernels that booted without problems were the
Gentoo (2004.1) and Knoppix (3.4) live cd kernels.
Knoppix (booted from cd) works generally well, but
hangs from time to time (especially when I access the
disks in mc).

I have an Asus P4P800 Deluxe mobo, and a P4 2.8GHz
with HT activated.
I uploaded a var/log/messages file at
http://aditsu.freeunixhost.com/messages.zip for your
reference (68KB zipped, 980KB unpacked). This is from
gentoo only.
The computer works flawlessly in windows xp.

Please help me out, so that all these wasted days
won't be in vain. I can provide any other necessary
information if I can understand how to obtain it (I'm
not a linux expert).

I'd appreciate if you could cc me in the replies.

Thanks
Adrian

Had the same problem last week. After some googling the solution was to 
change the settings of the SATA port in BIOS to Enhanced Mode, SATA only.

Thanks, but I don't have any SATA disk; my BIOS IDE
settings are: Enhanced Mode, P-ATA only.
And my main problem seems to be the "disabling irq"
thing.

Regards,
Adrian

I don't have any SATA disk either. Though it did make a difference!
Have you actually tried to change it?

I tried it now, and it indeed made a huge difference!
And the effect was not a big failure to detect the
disks as I expected, but.. the first kernel I tried
(2.6.8-rc1) booted without any noticeable error or
problem! (and windows xp was not affected)

I'm completely baffled about this, and I'm left with
two questions:
1. why?
2. does it have any negative side-effect (e.g. related
to disk transfer performance)?

Thanks a lot!
Adrian
