Hi! I used to have two cpus, and Thinkpad X60 should have two cores, but I only see one on 4.10-rc1. This machine went through many suspend/resume cycles. When backups finish, I'll try -rc2. pavel@duo:~$ uname -a Linux duo 4.10.0-rc1+ #304 SMP Mon Dec 26 10:33:24 CET 2016 i686 GNU/Linux pavel@duo:~$ zcat /proc/config.gz | grep SMP CONFIG_X86_32_SMP=y CONFIG_GENERIC_SMP_IDLE_THREAD=y CONFIG_SMP=y # CONFIG_X86_BIGSMP is not set CONFIG_PM_SLEEP_SMP=y pavel@duo:~$ cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 14 model name : Genuine Intel(R) CPU T2400 @ 1.83GHz stepping : 8 cpu MHz : 1833.000 cache size : 2048 KB physical id : 0 siblings : 1 core id : 0 cpu cores : 1 apicid : 0 initial apicid : 0 fdiv_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 10 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx constant_tsc arch_perfmon bts aperfmperf pni monitor vmx est tm2 xtpr pdcm dtherm bugs : bogomips : 3657.62 clflush size : 64 cache_alignment : 64 address sizes : 32 bits physical, 32 bits virtual power management: pavel@duo:~$ Pavel -- (english) http://www.livejournal.com/~pavelmachek (cesky, pictures) http://atrey.karlin.mff.cuni.cz/~pavel/picture/horses/blog.html
