oops while booting with recent git kernel

oops while booting with recent git kernel

[Arkadiusz Miskiewicz]

Not sure if it's worth to report this before all initial merges happen but 
here it is anyway.

git kernel with latest commit:
commit fd048088306656824958e7783ffcee27e241b361
Date:   Sat Oct 11 13:23:48 2008 -0700

booted on thinkpad z60m results with such oops:

Config used:

Just tested with today git (latest commit is):

commit a447c0932445f92ce6f4c1bd020f62c5097a7842
Author: Steven Whitehouse <swhiteho@redhat.com>
Date:   Mon Oct 13 10:46:57 2008 +0100

and the oops still happens, so I guess this is real problem.

Thanks for the report.

It seems to be an instance of this (known bad) code:
http://lkml.org/lkml/2008/9/4/386

So hopefully it will be fixed soon.

should be fixed by in upstream.. already

commit 1cf44baad76b6f20f95ece397c6f643320aa44c9

    IO resources: fix/remove printk

    Andrew Morton noticed that the printk in kernel/resource.c was buggy:

    | start and end have type resource_size_t.  Such types CANNOT be printed
    | unless cast to a known type.
    |
    | Because there is a %s following an incorrect %lld, the above code will
    | crash the machine.

    ... and it's probably quite unneeded as well, so remove it.
