I have no current insight as to whether there's a kernel issue here, but why are you trying to put actual device nodes in an actual filesystem as part of a build process? It's extremely straightforward to emit devices nodes in cpio format, and IMO it's far *more* straightforward to do that than to make a whole directory, try to get all the modes right, and cpio it up. I wrote an absolutely trivial tool for this several years ago: https://github.com/amluto/virtme/blob/master/virtme/cpiowriter.py it would be barely more complicated to strip the trailer off an cpio file from some other source, add some device nodes, and stick the trailer back on. But it's also really, really, really easy to emit an entire, functioning cpio-formatted initramfs from plain user code with no filesystem manipulation at all. This also makes that portion of the build reproducible, which is worth quite a bit IMO. --Andy _______________________________________________ linux-snps-arc mailing list linux-snps-arc@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-snps-arc
