Hi Clint,

the following CPU is detected as UNKNOW and hence causes a full tune with 3.8.2 and all errata applied:

processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 29
model name : Intel(R) Xeon(R) CPU X7460 @ 2.66GHz
stepping : 1
cpu MHz : 2666.763
cache size : 16384 KB
physical id : 0
siblings : 6
core id : 0
cpu cores : 6
fpu : yes
fpu_exception : yes
cpuid level : 11
wp : yes
flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx lm constant_tsc arch_perfmon pebs bts rep_good pni monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr dca sse4_1 lahf_lm
bogomips : 5337.16
clflush size : 64
cache_alignment : 64
address sizes : 40 bits physical, 48 bits virtual
power management:

Analog to the model 23 detection problem the suggested fix is to change line 298 of CONFIG/src/backend/archinfo_x86.c to

case 15: ; case 23: ; case 29:
iret = IntCore2Duo;
break;

Cheeers,

Michael

    Michael,

    Thank you very much for the patch. I usually ask people to start the report as a support request, and I escalate to the bug tracker, but since you are right, I can't bitch :)

    I have corrected this for the 3.9 series, where I ID it as an IntCore2 (rather than IntCoreDuo).

    Thanks,
    Clint

    This should be fixed in 3.9.6.

    I believe this should be fixed in 3.8.3. Please reopen if this is not the case.
