Subject: Boot failure with next-20120208

Hi all,

Just a quick note to say I got a boot OOPs with next-20120208 and 9 on a
Power7 blade (my other PowerPC boot tests are ok.  I'll investigate this
further on Monday.

The line referenced below is:

BUG_ON(!kobj || !kobj->sd || !attr);

in sysfs_create_file().
