Did a new install, the new kernel can't load modules: # modprobe nfsv3 modprobe: ERROR: could not insert 'nfsv3': Exec format error
Odd. Never had this before. The module file itself is a regular 64-bit ELF file, just as it should be (compared to a working module on another machine) gcc is 4.8.4 as supplied by a recent stage3-amd64-20150709.tar.bz2: # gcc -v Using built-in specs.

Module loading works just fine when booted from the Gentoo minimal install image. So, what dumbass n00b error did I make today? -- Alan McKinnon alan.mckin...@gmail.com
