Hi, I have a chance, for a few hours, to test a machine build upon Xeon MP "Dunnington" CPUs, with 2 CPUs with 6 core each (2x6). Everything works fine except that only 4 cores are activated from each CPU: CPU: Genuine Intel(R) CPU _at_ 2.13GHz (2133.35-MHz K8-class CPU) Origin = "GenuineIntel" Id = 0x106d0 Stepping = 0 Features=0xbfebfbff<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,HTT,TM,PBE> Features2=0xce33d<SSE3,RSVD2,MON,DS_CPL,VMX,TM2,SSSE3,CX16,xTPR,PDCM,DCA,<b19>> AMD Features=0x20100800<SYSCALL,NX,LM> AMD Features2=0x1<LAHF> Cores per package: 6 usable memory = 8576860160 (8179 MB) avail memory = 8281669632 (7898 MB) ACPI APIC Table: <111607 APIC1739> FreeBSD/SMP: Multiprocessor System Detected: 8 CPUs cpu0 (BSP): APIC ID: 0 cpu1 (AP): APIC ID: 1 cpu2 (AP): APIC ID: 2 cpu3 (AP): APIC ID: 3 cpu4 (AP): APIC ID: 8 cpu5 (AP): APIC ID: 9 cpu6 (AP): APIC ID: 10 cpu7 (AP): APIC ID: 11 Note that it detects 6 cores per package (which is correct) but then proceeds to say 8 CPUs total are detected. Entire dmesg is here: http://people.freebsd.org/~ivoras/dmesg/mp6-dmesg.txt Output of mptable is also missing the CPUs: -- Processors: APIC ID Version State Family Model Step Flags 0 0x14 BSP, usable 6 13 0 0xbfebfbff 8 0x14 AP, usable 6 13 0 0xbfebfbff 1 0x14 AP, usable 6 13 0 0xbfebfbff 2 0x14 AP, usable 6 13 0 0xbfebfbff 3 0x14 AP, usable 6 13 0 0xbfebfbff 9 0x14 AP, usable 6 13 0 0xbfebfbff 10 0x14 AP, usable 6 13 0 0xbfebfbff 11 0x14 AP, usable 6 13 0 0xbfebfbff -- If any quick fixes are found within the next few hours, I can test them. This is 7-STABLE.Received on Tue Jul 01 2008 - 13:56:31 UTC
