Hey, everyone, I'm sorry it took me so long! This issue is important to everyone. So what follows will be kind of a big dump of information, but I don't know what all will be meaningful to everyone. So I've got 1) General information, 2) BIOS-reported information, and 3) dmesg | grep microcode 4) cat /proc/cpuinfo. 1) General Information OEM: CyberPowerPC Model Marketing Name: Fangbook III BX6 2) BIOS-Reported Information BIOS Version: E16J2ICP.10E EC Version 16J2ECP1 Ver5.06 CPU: Intel Core i7-5700HQ Stepping: 40671 Microcode patch: d (Note, before boot...) 3) dmesg | grep microcode -- on microcode 0xd -- [ 0.432493] microcode: CPU0 sig=0x40671, pf=0x20, revision=0xd [ 0.432498] microcode: CPU1 sig=0x40671, pf=0x20, revision=0xd [ 0.432503] microcode: CPU2 sig=0x40671, pf=0x20, revision=0xd [ 0.432508] microcode: CPU3 sig=0x40671, pf=0x20, revision=0xd [ 0.432513] microcode: CPU4 sig=0x40671, pf=0x20, revision=0xd [ 0.432518] microcode: CPU5 sig=0x40671, pf=0x20, revision=0xd [ 0.432522] microcode: CPU6 sig=0x40671, pf=0x20, revision=0xd [ 0.432528] microcode: CPU7 sig=0x40671, pf=0x20, revision=0xd [ 0.432559] microcode: Microcode Update Driver: v2.00 , Peter Oruba -- on microcode 0x12 -- [ 0.000000] microcode: CPU0 microcode updated early to revision 0x12, date = 2015-06-19 [ 0.076100] microcode: CPU1 microcode updated early to revision 0x12, date = 2015-06-19 [ 0.083977] microcode: CPU2 microcode updated early to revision 0x12, date = 2015-06-19 [ 0.091894] microcode: CPU3 microcode updated early to revision 0x12, date = 2015-06-19 [ 0.434008] microcode: CPU0 sig=0x40671, pf=0x20, revision=0x12 [ 0.434014] microcode: CPU1 sig=0x40671, pf=0x20, revision=0x12 [ 0.434019] microcode: CPU2 sig=0x40671, pf=0x20, revision=0x12 [ 0.434023] microcode: CPU3 sig=0x40671, pf=0x20, revision=0x12 [ 0.434028] microcode: CPU4 sig=0x40671, pf=0x20, revision=0x12 [ 0.434033] microcode: CPU5 sig=0x40671, pf=0x20, revision=0x12 [ 0.434037] microcode: CPU6 sig=0x40671, pf=0x20, revision=0x12 [ 0.434043] microcode: CPU7 sig=0x40671, pf=0x20, revision=0x12 [ 0.434075] microcode: Microcode Update Driver: v2.00 , Peter Oruba 4) cat /proc/cpuinfo (showing CPU 0 only) -- on microcode 0xd -- processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 71 model name : Intel(R) Core(TM) i7-5700HQ CPU @ 2.70GHz stepping : 1 microcode : 0xd cpu MHz : 2113.171 cache size : 6144 KB physical id : 0 siblings : 8 core id : 0 cpu cores : 4 apicid : 0 initial apicid : 0 fpu : yes fpu_exception : yes cpuid level : 20 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 pdpe1gb rdtscp lm constant_tsc arch_perfmon pebs bts rep_good nopl xtopology nonstop_tsc a perfmperf eagerfpu pni pclmulqdq dtes64 monitor ds_cpl vmx est tm2 ssse3 fma cx16 xtpr pdcm pcid sse4_1 sse4_2 x2apic movbe popcnt tsc_deadline_timer aes xsave avx f16c rdrand lahf_lm abm 3dnowprefetch ida arat epb pln pts dtherm intel_pt tpr_shadow vnmi flexpriority ept vpid fsgsbase tsc_adjust bmi1 avx2 smep bmi2 erms invpcid rdseed adx smap xsaveopt bugs : bogomips : 5389.86 clflush size : 64 cache_alignment : 64 address sizes : 39 bits physical, 48 bits virtual power management: -- on microcode 0x12 -- processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 71 model name : Intel(R) Core(TM) i7-5700HQ CPU @ 2.70GHz stepping : 1 microcode : 0x12 cpu MHz : 2701.054 cache size : 6144 KB physical id : 0 siblings : 8 core id : 0 cpu cores : 4 apicid : 0 initial apicid : 0 fpu : yes fpu_exception : yes cpuid level : 20 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 pdpe1gb rdtscp lm constant_tsc arch_perfmon pebs bts rep_good nopl xtopology nonstop_tsc a perfmperf eagerfpu pni pclmulqdq dtes64 monitor ds_cpl vmx est tm2 ssse3 fma cx16 xtpr pdcm pcid sse4_1 sse4_2 x2apic movbe popcnt tsc_deadline_timer aes xsave avx f16c rdrand lahf_lm abm 3dnowprefetch ida arat epb pln pts dtherm intel_pt tpr_shadow vnmi flexpriority ept vpid fsgsbase tsc_adjust bmi1 avx2 smep bmi2 erms invpcid rdseed adx smap xsaveopt bugs : bogomips : 5390.35 clflush size : 64 cache_alignment : 64 address sizes : 39 bits physical, 48 bits virtual power management: When I "diffed" the /proc/cpuinfo outputs I saved off, only differences were in microcode of course, bogomips, and cpu MHz. The following commands have always returned no hits for me, even on the 0xd microcode that came stock: grep flags /proc/cpuinfo | grep tsx grep flags /proc/cpuinfo | grep rtm grep flags /proc/cpuinfo | grep hle If you need other information like the bridge, let me know. Thanks everyone so much for explaining the problem and providing a workaround. 0x12 works brilliantly for me. -- You are receiving this mail because: You are the assignee for the bug.
