Subject: WARNING: at /usr/src/linux-3.6.2/kernel/irq/irqdomain.c:743

Hello!

The kernel for my IBM Cell Broadband Engine cluster (IBM QS22 blades) does not 
boot anymore after I updated from 3.5.3-gentoo to 3.6.2-gentoo.

It issues a ton of warnings instead, which were not present earlier:
WARNING: at /usr/src/linux-3.6.2/kernel/irq/irqdomain.c:743

I can confirm the problem with a vanilla 3.6.2 kernel.

I attached several logs and configs:
* blade02-3.5.3-gentoo.boot-20121019.log
  Successful boot with the old 3.5.3-gentoo kernel
* blade02-3.6.2-gentoo.boot-20121019.log
  Failing boot with the new 3.6.2-gentoo kernel
* blade02-3.6.2-gentoo.config.diff
  Diff between 3.5.3-gentoo and 3.6.2-gentoo configs
* blade03-3.6.2.boot-20121019.log
  Failing boot with a vanilla Linux 3.6.2 kernel
* blade03-3.6.2.config
  Config of the vanilla Linux 3.6.2 kernel
  Same as for 3.6.2-gentoo, except that gentoo also has CONFIG_KCOPY=m

It would be nice if someone could help me debug the issue. If you need any 
more information, please do not hesitate to ask me.

Please CC me, as I am not on the list.

Best regards,
Dennis Schridde
