hmm, one thing I noticed in doc/README.SPL:

"When building SPL with DEBUG set you may also need to set CONFIG_PANIC_HANG
as in most cases do_reset is not defined within SPL."

not sure if that would help.

Also, it has a section about estimating stack usage.. not sure if this
implies that stack size is constrained in spl?  If so, maybe that is
related.  The new directory iterators do move the buffer for current
block of dir_entry's to the stack.  Reducing
CONFIG_FS_FAT_MAX_CLUSTSIZE might help.
