[Daniele Viganò <daniele.vigano@xxxxxxxxxxxxxxxxxxxx>]

The AMD microcode coming from linux-firmware - 1.79.6 is freezing 99% of
the times my 5 Dell PowerEdge M915 blades (4x64 Cores Opteron 6274,
currently with 3.0.4 BIOS).

This happens both at boot and also if I blacklist the 'microcode' module
and then I run 'modprobe microcode' after the system is up. To have
always a successful boot I had to blacklist the microcode module.

  The ucode used to be available here:
  http://www.amd64.org/support/microcode.html before the site went down
  last year.

  This AMD ucode fixes some severe lockup issues on AMD family 15h CPUs when under high load.
  The fix for erratum #759 being the most severe.

  Example thread discussing the lockup issues of #759: http://communities.vmware.com/thread/432033?start=30&tstart=0
