Hello The 3.13 kernel reports invalid L3 cache information in sysfs. 0x3f0 is not possible on this processor, it should be either 0x3f or 0xfc (there's exactly one L3 per NUMA node, with the same 6 cores in them).
Can you check whether the BIOS is also the same on these machines? (see files in /sys/class/dmi/id/) If the machine and BIOS are the same, then it's a regression in Ubuntu's 3.13 kernel. However that would be surprising since these AMD processors have been properly supported by Linux for several years already.
