ahh, here it is:

0dfe6e7ed47f ipmi: Turn off default probing of interfaces

Since Arnd says it's possible to have this hardware on an ARM platform,
I think backporting this fix may be appropriate.

Although, it looks like the only ARM defconfig that selects this driver
is mini2440_defconfig. So I'm uncertain how it gets turned on in
multi_v7_defconfig, particularly for the v3.10.y stable tree...

thx,

Jason.
