When it runs with one processor and hyperthreading off, or two processors and hypperthreading on, everything is fine. However when I turn off either multiprocessor or hyperthreading options in BIOS setting, the SMP kernel will not be able to boot. System config: FreeBSD 4.6.2-R GENERIC kernel config with SMP and APIC options The behavior: With one processor and hyperthreading turned on, the kernel hung at the very start with the following message: panic: pmap_bootstrap: no local apic! mp_lock = 00000008; cpuid = 0; lapic.id = 00000000 uptime: 0s With two processors and hyperthreading turned off, the kernel began probing devices, and hung at this spot: APIC_IO: Testing 8254 interrupt delivery It looks like the mainboard or BIOS has some implementation problem, any suggestions? And this is the mptable when booting with both multiprocessor and hyperthreading turned on: =============================================================================== MPTable, version 2.0.15 ------------------------------------------------------------------------------- MP Floating Pointer Structure: location: EBDA physical address: 0x0009cc30 signature: '_MP_' length: 16 bytes version: 1.1 checksum: 0x0c mode: Virtual Wire ------------------------------------------------------------------------------- MP Config Table Header: physical address: 0x0009eea0 signature: 'PCMP' base table length: 476 version: 1.1 checksum: 0xd4 OEM ID: 'OEM ID ' Product ID: 'PRODUCT ID ' OEM table pointer: 0x00000000 OEM table size: 0 entry count: 48 local APIC address: 0xfee00000 extended table length: 0 extended table checksum: 0 ------------------------------------------------------------------------------- MP Config Base Table Entries: -- Processors: APIC ID Version State Family Model Step Flags 0 0x14 BSP, usable 15 2 4 0x3febfbff 1 0x14 AP, usable 15 2 4 0x3febfbff 6 0x14 AP, usable 15 2 4 0x3febfbff 7 0x14 AP, usable 15 2 4 0x3febfbff -- Bus: Bus ID Type 0 PCI 1 PCI 2 PCI 3 PCI 4 PCI 5 PCI 6 PCI 7 PCI 8 ISA -- I/O APICs: APIC ID Version State Address 14 0x20 usable 0xfec00000 13 0x20 usable 0xfec80000 12 0x20 usable 0xfec80400 11 0x20 usable 0xfec82000 10 0x20 usable 0xfec82400 -- I/O Ints: Type Polarity Trigger Bus ID IRQ APIC ID PIN# ExtINT active-hi edge 8 0 14 0 INT active-hi edge 8 1 14 1 INT active-hi edge 8 0 14 2 INT active-hi edge 8 3 14 3 INT active-hi edge 8 4 14 4 INT active-hi edge 8 5 14 5 INT active-hi edge 8 6 14 6 INT active-lo level 8 7 14 7 INT active-hi edge 8 8 14 8 INT active-lo level 8 9 14 9 INT active-lo level 8 10 14 10 INT active-hi edge 8 11 14 11 INT active-hi edge 8 12 14 12 INT active-hi edge 8 13 14 13 INT active-hi edge 8 14 14 14 INT active-hi edge 8 15 14 15 INT active-lo level 0 29:A 14 16 INT active-lo level 0 29:B 14 19 INT active-lo level 0 29:C 14 18 INT active-lo level 0 31:A 14 16 INT active-lo level 0 31:B 14 17 INT active-lo level 2 31:A 13 23 INT active-lo level 3 1:A 12 0 INT active-lo level 3 1:B 12 1 INT active-lo level 5 1:A 11 0 INT active-lo level 5 31:A 11 23 INT active-lo level 6 31:A 10 23 INT active-lo level 7 0:A 14 16 -- Local Ints: Type Polarity Trigger Bus ID IRQ APIC ID PIN# ExtINT active-hi edge 8 0 255 0 NMI active-hi edge 0 0:A 255 1 =============================================================================== jsli. _________________________________________________________________ MSN 相簿提供您最簡單的方式分享並列印您的相片，請移至： http://photos.msn.com.hk/support/worldwide.aspx To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-smp" in the body of the message
