Did you use a config file for 4.9.76 to build for kernel 3.4.52?
If so, this might not be a good idea. CONFIG options may vary quit a
bit between different kernel releases, which could mean trouble.
Using an older config to build a newer kernel is usually OK. While
going the other way may not work as expected.
Also, I've noticed that your 'make silentconfig' aborted. You want to
take a closer look at that too. Try running 'make oldconfig' and see
what transpires.
Another point to consider is using a more recent kernel, as 3.4.52,
which was released back in 2013, may no longer be supported.
