Thanks, but I'm quite aware of that. :)

I suspect this might be a PPC specific kernel build system issue related
to Modules.symvers, so I'm CC'ing linuxppc-dev and including the
original post below for reference. Any hints appreciated.

Actually, now that my x86_64 box is back up, it happens there as well,
so maybe it's related to the Debian toolchain or kernel packaging.
Apologies to linuxppc-dev for the false alarm.
