--nextPart2136748.vReAhr5N5d Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: quoted-printable Content-Disposition: inline I'm running a 5.4-STABLE system (updated as of May 16). My kernel is=20 basically GENERIC with a few small tweaks, like commenting out extraneous=20 "cpu" lines and adding "options SMP". My problem is that although dmesg shows every sign of having launched both= =20 logical CPUs: $ dmesg | grep -i cpu CPU: Intel(R) Xeon(TM) CPU 2.40GHz (2392.05-MHz 686-class CPU) Hyperthreading: 2 logical CPUs =46reeBSD/SMP: Multiprocessor System Detected: 2 CPUs cpu0 (BSP): APIC ID: 0 cpu1 (AP): APIC ID: 1 cpu0: <ACPI CPU> on acpi0 cpu1: <ACPI CPU> on acpi0 SMP: AP CPU #1 Launched! =2E.. running "top" only shows "0" in the CPU column for every task. I don= 't=20 see anything out of place in sysctl: $ sysctl -a | grep -i hlt machdep.cpu_idle_hlt: 1 machdep.hlt_cpus: 2 machdep.hlt_logical_cpus: 0 and /boot/loader.conf is all but empty. Honestly, I don't really know how= =20 long this has been going on. top used to show both 0 and 1 in the C column= =20 and I'm not exactly sure when it stopped. Any ideas? =2D-=20 Kirk Strauser --nextPart2136748.vReAhr5N5d Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- iD8DBQBCk04A5sRg+Y0CpvERAvpuAJ9ql1V9ERG5v/9c00ZGXKgVxydamwCghQwM 7QW6tch2kWs9ELv/Jb1BsP4= =A3J3 -----END PGP SIGNATURE----- --nextPart2136748.vReAhr5N5d--
