Disabling CONFIG_IDE made my machine boot, as it was using libata
anyway.

init_irq? hmm...

this comes from ide-generic
(Generic IDE host driver)

Kamalesh/Pavel:

Could you try latest git and see if the OOPS is still there?

[ Yeah, I'm unable to reproduce it. :( ]

Hi Bart,

The panic is reproducible with the 2.6.24-git16 kernel, the call trace is

Thanks, I again reviewed ide-probe.c changes but nothing seems wrong...

Could you please bisect it down to the guilty commit?

> BUG: unable to handle kernel paging request at ffffffffffffffa0
> IP: [<ffffffff80415673>] init_irq+0x188/0x444

Please also try disassembling init_irq using gdb so we see where it fails.

Kamalesh, were you able to bisect this down? I just got hit by the
same panic on a 4-way x86_64, with 2.6.24-git22.

Hi Nish,

Thanks for the detailed analysis and sorry for the bug.

I think that this may has been just fixed by Andi's recent hwif_to_node()
fix (patch below, it is in Linus' tree already), could please verify this?

commit 1f07e988290fc45932f5028c9e2a862c37a57336
Author: Andi Kleen <andi@firstfloor.org>
Date:   Mon Feb 11 01:35:20 2008 +0100

    Prevent IDE boot ops on NUMA system
    
    Without this patch a Opteron test system here oopses at boot with
    current git.
    
    Calling to_pci_dev() on a NULL pointer gives a negative value so the
    following NULL pointer check never triggers and then an illegal address
    is referenced.  Check the unadjusted original device pointer for NULL
    instead.

Hi Bart,
Thanks !! the patch solves the kernel panic but when after applying the patch,kernel is not
able to mount the filesystem and panics, am i not sure what is likely causing the panic.

Creating root device.
Mounting root filesystem.
mount: could not  find filesystem
Kernel panic - not syncing: Attempted to kill init!

Is

- the commit 36501650ec45b1db308c3b51886044863be2d762 with Andi's fix applied

or

- the commit f6fb786d6dcdd7d730e4fba620b071796f487e1b
  (the one before commit 36501650ec45b1db308c3b51886044863be2d762)

working for you?

Is IDE actually used for the boot device?

[ Please send a dmesg output from the working system. ]

No, the commit before the commit 36501650ec45b1db308c3b51886044863be2d762 did not either work, i
get the same kernel panic.

Hi,

Thanks for pointing the patch, I do not have the SES config option enabled, 
then too i tried your patch, but that does not solve the panic. The kernel
panic's with the same panic message as before. I have attached the .config 
file which i am using, please let me know if i am missing out/getting wrong
any option in the configuration.
