Thanks for the report.  We do need to check if alloc_nvdimm_map fails.
My guess as to why it is failing the call to request_mem_region().
Can you try the attached patch, and send the kernel log as well as the
contents of /proc/iomem?

libnvdimm: fix devm_nvdimm_memremap() error path

From: Dan Williams <dan.j.williams@intel.com>

The internal alloc_nvdimm_map() helper might file, particularly if the
memory region is already busy.  Report request_mem_region() failures and
check for the failure.

OK, I've tried this patch, and there is no panic anymore, however the
request region offset
seems a little weird, it is not in the iomem space, not sure if I'm
doing the right testing.
please refer to attachment the kernel boot log , iomem address space
and the insmod nfit_test.ko message.
I'm testing like this:
modprobe dax
modprobe dax_pmem
modprobe libnvdimm
modprobe nd_blk
modprobe nd_btt
modprobe nd_e820
modprobe nd_pmem
modprobe nfit
insmod nfit_test_iomap.ko
insmod nfit_test.ko

For the unit tests to operate you need the unit test version of
nfit.ko loaded.  All of these dependencies are figured out
automatically if you have performed the following build / installation
steps as recommended by the ndctl readme [1]:

make M=tools/testing/nvdimm/
sudo make M=tools/testing/nvdimm/ modules_install
sudo make modules_install

...after that is complete you only need to perform:

modprobe nfit_test

...and modprobe will figure out all the right dependencies and load
all the other modules.

In fact to run the unit tests you don't even need to load nfit_test
ahead of time.  The unit test itself takes care of that.
