Hmm. It *may* indicate some kind of build problem. The build I got
that for was an allmodconfig build, but I had interrupted the previous
one in the middle, because I wanted to re-do the build with the proper
version number. I wonder if there's some race where if you ^C the
build at just the right time the CRC's don't get done right?

Michal: any ideas? The errors are of the type:

WARNING: "ring_buffer_event_data" [*/*/*.ko] has no CRC!

and maybe there's a problem with genksyms.c leaving an empty (or
incomplete) file around when interrupted, and it then gets reused the
next time around?
