Please update amd-ucode in linux-firmware

https://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/commit/?id=31f6b3076bab3c4b65f67fdb232f4579ed828b4f

Files:
amd-ucode/microcode_amd.bin
amd-ucode/microcode_amd_fam15h.bin

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
Dell + others have already updated BIOS updated microcode: http://www.dell.com/support/drivers/au/en/19/DriverDetails?driverId=HPP5C

Hello Grant, or anyone else affected,

Accepted linux-firmware into precise-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/linux-firmware/1.79.6 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

Tested and worked for me.

TEST CASE:
1. Installed package and loaded kernel module microcode, AMD microcode loaded as expected.
2. update-initramfs worked as expected.
3. System reboot, no unexpected results.

VERIFICATION DONE
No issues with test above. System is stable without unexpected lock-ups under high load.

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.
