Below are excerts from email exchange between Christian and Vladimir Kozlov:

Vladimir:

family 6 model 23 stepping 10  is Intel(R) Core(TM)2 Duo CPU

The problem is next (even newest cpus has it value only 11u):

>     std_max_function  = 13U

Is it possible some one stomp bits into the field (? I can't find such cpu here. Christian could you stop when cpuid assembler code is executed at the line 129 and check what value in eax?

Christian:

Sure:
 (dbx) p $eax
 $eax = 13U

Introduced by changes for 6964774 which added cpuid
processor topology code. Some cpus have max cpuid >= 11
but do not support processor topology:

vendor_id    : GenuineIntel
cpu family    : 6
model        : 23
model name    : Intel(R) Xeon(R) CPU           E5472  @ 3.00GHz
stepping    : 10
cpu MHz        : 2403.000
cpu cores    : 4
cpuid level    : 13


Solution:
Check that cpuid returns valid values for processor
topology (not zeros) and use old code if they are invalid.
