I managed to get to userspace on one boot, and got this.

kobject ffff88023d93f518 has been corrupted (magic 0x6b6b6b6b).  Please enable kobject debugging for full debug.

That looks like SLAB_POISON. Incompatibility between the two options ?

For some reason, even though I have DEBUG_KOBJECT on, I didn't get extra messages output.
