Bug#735006: gcc-4.9: amd64 kernel gives error alg: hash: Chunking test 1 failed for hmac(md5-generic)

[Arthur Marsh <arthur.marsh@internode.on.net>]

Package: gcc-4.9
Version: 4.9-20140110-1
Severity: normal

Dear Maintainer,
*** Please consider answering these questions, where appropriate ***

   * What led up to the situation?

building current git head kernel with gcc-4.9

CONCURRENCY_LEVEL=6 MAKEFLAGS="CC=gcc-4.9 LD=ld.gold CFLAGS=-march=athlon64" \
make-kpkg --config menuconfig --initrd linux-image 

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

make clean followed by rebuilding current git head kernel with gcc-4.8 worked

   * What was the outcome of this action?

when attempting a cifs mount on AMD64 running a kernel built with gcc-4.9 
I received the following error:

   * What outcome did you expect instead?
