What I did for these tests: installed 6.0-RELEASE/i386 (booted with with apic disabled) cd /usr/src; make kernel KERNCONF=SMP connect a serial console reboot at the boot menu I hit 6 OK set console=comconsole Then disable apic: The dmesg is in http://xocolatl.com/rfaulds/freebsd-acpi/test2-SMP-dmesg-apic-disabled This boots ok. I repeat the same procedure but this time I disable acpi: http://xocolatl.com/rfaulds/freebsd-acpi/test2-SMP-dmesg-acpi-disabled This won't boot, but I left it for about 20 minutes and it printed the message that it had attached pass0 and da0. After an hour or so, it was still sitting complaining that "mpt1: Timedout requests already complete. Interrupts may not be functioning." I repeated these steps with an Adaptec 2130SLP controller and I get the same behavior. I also discovered the error I made originally WRT disabling APIC along with ACPI. Choosing option 2 from the boot menu (or setting hint.acpi.0.disabled=1 at the loader prompt) of amd64 6.0-REL also disables APIC. I do not know why but it turned out to be a feature in my case. Suggestions?

The BIOS toggle just changes the HT CPUs to be listed as disabled in the MADT table ACPI uses. The 'Hyperthreading' printf in the dmesg is based on reading the registers from the CPU and is output even in a UP kernel. Your MP table looks ok as well, so I'm not sure why a dmesg with no ACPI is not finding your CPUs. How did you disable ACPI, did you boot using safe mode? If so, try breaking into the loader and just disable ACPI via set hint.acpi.0.disabled=1 Safe mode disables SMP support as well as ACPI. -- John Baldwin <jhb@FreeBSD.org> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve" = http://www.FreeBSD.org
