The device is not attaching because bus_dma_tag_create function fails
with the error ENOMEM. (in line 300, safe.c). I have changed
BUS_DMA_ALLOCNOW flag in bus_dma_tag_create to BUS_DMA_COHERENT and
the panic disappears. BUS_DMA_COHERENT was just taken randomly (as in
some other flag) with no idea about it's use or purpose.

The PR Number is 110662. I have tried to put as much information as
possible, I am always ready to provide additional details or do some
testing/debugging.
