It's ndctl from git master, hence 64.1.
I am using a similar software kernel+ndctl on a machine with real
nvdimms, no problem there. It's only the machine with fake nvdimm using
memmap that show this issue.
Hmm, all my guesses are coming up empty... which usually means there
is indeed a bug. Let me try some experiments here, but I may need to
send you a debug patch for more info. Thanks for the memmap=
insight... I do test with that, but let me see if there is something
specific about your config.
