Can you send the output of this command on both nodes?
cat /sys/devices/system/cpu/cpu{?,??}/cache/index3/shared_cpu_map | uniq -c
And send the XML output of lstopo on both nodes too (lstopo foo.xml and
send foo.xml).
I want to check that this is indeed a kernel regression.
Thanks

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
