We have been seeing panics booting NUMA SPARSEMEM kernels on x86_32 hardware, while trying to allocate node local memory in early boot. These are caused by a miss-allocation of the node pgdat structures when numa remap is disabled.
Following this email are two patches, the first reenables numa remap for SPARSEMEM as the underlying bug has now been fixed. The second hardens the pgdat allocation in the face of there being no numa remap for a particular node (which may still occur).
