I have the same processor at home running on 10.04 64-bit. We've had
issues with running 32-bit OSes on 64-bit processors. I thought these
were worked out, but there must be another issue.

Try configuring volk with "configure --with-lv_arch="generic 64 mmx
sse sse2 sse3 ssse3 sse4_a sse4_1 sse4_2" or whatever simd flavors you
want to support. Let me know if that works.

I also need to put the --with-lv_arch as a configuration option in the
gnu radio configure.

Thanks,
Tom
