Hi, I have a IBM x3550 running 7-stable. The CPU is CPU: Intel(R) Xeon(R) CPU E5345 @ 2.33GHz (11368.47-MHz K8-class CPU) Origin = "GenuineIntel" Id = 0x6fb Stepping = 11 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=0x4e3bd<SSE3,RSVD2,MON,DS_CPL,VMX,EST,TM2,SSSE3,CX16,xTPR,PDCM,DCA> AMD Features=0x20100800<SYSCALL,NX,LM> AMD Features2=0x1<LAHF> Cores per package: 4 But the dev.cpu.0 shows dev.cpu.0.freq: 11311 dev.cpu.0.freq_levels: 11311/-1 9897/-1 8483/-1 7069/-1 5655/-1 4241/-1 2827/-1 1413/-1 The max frequency 11311 (11.3GHz?) is far larger than it should be (2.33GHz). It causes something wrong on this system, for example: [huan@cml2 ~]$ time sleep 1 real 0m4.929s user 0m0.000s sys 0m0.000s Any suggestion? Thanks a lot~ Tz-Huan
