Hello!
I have a Pentium D box, running 6.2-RELEASE. In dmesg, I see CPU#1
launched, but I never see any process running on it, and mptable shows
cluster-one# mptable -verbose

SMP: AP CPU #1 Launched!
The kernel is, of course, SMP.
What can I do, where can I search for solution?
Second core IS enabled in BIOS
cluster-one# sysctl hw | grep cpu
hw.ncpu: 2
hw.acpi.cpu.cx_supported: C1/0
hw.acpi.cpu.cx_lowest: C1
hw.acpi.cpu.cx_usage: 100.00%
cluster-one# sysctl machdep | grep cpu
machdep.cpu_idle_hlt: 1
machdep.hlt_cpus: 2
machdep.hlt_logical_cpus: 0
machdep.logical_cpus_mask: 2
so second CPU is halted, attempt to start it with sysctl does not help
Alex.
