hi. I just posted Bug#778942. After posting, I rebooted and studied my package listing for "linux" related packages. Apparently I had been using the i386 linux-kbuild package!
I have no idea how that got there, this has always been a 64-bit system. ii linux-kbuild-3.16 3.16-3 i386 K Yikes! Did a dependency wire get crossed somewhere? Suffice to say, after aptitude install linux-kbuild-3.16:amd64 (uninstalling linux-kbuild-3.16:i386) Everything works as expected! Thank you so much for making debian awesome! have a day.yad jdpf
