Hello,
I tried "make check" of ndctl command on the kernel of libnvdimm-for-next
branch(*),
but I feel its kernel is unstable when nfit_test.ko module is loaded.
(*) git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
libnvdimm-for-next
The newest commit is f5705aa8cfed
Here is console logs when the kernel was paniced, and I'll attach the kernel
config file.
Does anyone know how to solve this? Am I something wrong?
