Re: [solved]Intel microcode necessary?

Ha, ha, for someone who likes puzzles:

I have an Atom 330 processor (dual-core with hyperthreading), so it appears as 4 CPUs.

With the new intel-ucode.img in syslinux.cfg, this is what I get:

[    0.000000] CPU0 microcode updated early to revision 0x219, date = 2009-04-10
[    0.556420] microcode: CPU0 sig=0x106c2, pf=0x8, revision=0x219
[    0.556453] microcode: CPU1 sig=0x106c2, pf=0x8, revision=0x213
[    0.556481] microcode: CPU2 sig=0x106c2, pf=0x8, revision=0x219
[    0.556510] microcode: CPU3 sig=0x106c2, pf=0x8, revision=0x213
[    0.556808] microcode: Microcode Update Driver: v2.00 <tigran@aivazian.fsnet.co.uk>, Peter Oruba

So yeah, it applied the microcode (early) to just one core.
You can see above that CPU0 and CPU2 (same core) are 0x219, the other core (CPU1,CPU3) remained at 0x213.

Nice, isn't it?

I had the same problem on my intel E2200, only one core updated.
Solved here for me with Kernel 3.17.4...

Solved here for me with Kernel 3.17.4...

Now that 3.17.4 is out of testing, I installed too and both cores are updated.
Glad to know I was not alone and it is fixed now for both of us
