I'm looking into it. -next is all kinds of broken. > :( Just FYI, in case folks are still testing -next: One other issue that I was hitting was that for many of the commits in -next kernel modules wouldn't load, which meant that my /dev/pmem0 device wasn't showing up because I have libnvdimm compiled as a module. I bisected that issue to this commit: commit d1091c7fa3d5 ("objtool: Improve detection of BUG() and other dead ends") It looks like Xiong also found this issue: https://lkml.org/lkml/2017/3/2/114 And Linus found it: https://lkml.org/lkml/2017/2/28/794 - Ross
