I can, but it no longer boots... Will keep trying.
I've gone through my system.map and pulled out the call stack, if that
helps. I put a printk in sysfs_add_one, and it appears it is being
called with sd->s_name = 'e00082a8.dma'

I believe the DMA is being added twice, because it occurs twice within the mpc8313erdb.dts device tree. Once by itself, and once within a sleep-nexus.
Is that right / normal ?

No, that looks like a mismerge. There should only be the node under
sleep-nexus.

I am having the same problem with badness at fs/sysfs/dir.c on the
MPC8313ERDB. More importantly my custom board based on this development
board will not boot past "loading device tree." Are there any other
mismerges in this file? If we fix the dts file how do we fix the
official dts file and when would that fix be put in place?

No, that looks like a mismerge. There should only be the node under=20

That's probably unrelated.

Not that I know of.

With a patch.

When the patch is applied. :-)
