------=_Part_769_12954910.1101814185802 Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: 7bit Content-Disposition: inline Strange problem. On an IBM xSeries 335 machine with TWO P4 HTT cpus (mptable, dmesg output enclosed) FreeBSD -CURRENT will sometimes detect both the physical CPUs and will sometimes detect only one. FreeBSD 5.3 reliably detects the 2 physical / 4 logical CPUs that are present. Any suggestions on how to debug this? ------=_Part_769_12954910.1101814185802 Content-Type: text/plain; name=mptable.txt; charset=us-ascii Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename="mptable.txt" =============================================================================== MPTable, version 2.0.15 ------------------------------------------------------------------------------- MP Floating Pointer Structure: location: EBDA physical address: 0x0009e140 signature: '_MP_' length: 16 bytes version: 1.4 checksum: 0x97 mode: Virtual Wire ------------------------------------------------------------------------------- MP Config Table Header: physical address: 0x0009f010 signature: 'PCMP' base table length: 260 version: 1.4 checksum: 0x36 OEM ID: 'IBM ENSW' Product ID: 'TURQUIOSESMP' OEM table pointer: 0x00000000 OEM table size: 0 entry count: 24 local APIC address: 0xfee00000 extended table length: 208 extended table checksum: 84 ------------------------------------------------------------------------------- MP Config Base Table Entries: -- Processors: APIC ID Version State Family Model Step Flags 0 0x14 BSP, usable 15 2 9 0x0301 6 0x14 AP, usable 15 2 9 0x0301 -- Bus: Bus ID Type 0 PCI 1 PCI 2 PCI 3 ISA -- I/O APICs: APIC ID Version State Address 14 0x11 usable 0xfec00000 13 0x11 usable 0xfec01000 12 0x11 usable 0xfec02000 -- I/O Ints: Type Polarity Trigger Bus ID IRQ APIC ID PIN# INT conforms conforms 3 1 14 1 INT conforms conforms 3 0 14 2 INT conforms conforms 3 4 14 4 INT conforms conforms 3 6 14 6 INT conforms conforms 3 8 14 8 INT conforms conforms 3 12 14 12 INT conforms conforms 3 13 14 13 INT conforms conforms 3 14 14 14 INT conforms conforms 3 15 14 15 INT conforms conforms 0 1:A 13 10 INT conforms conforms 0 15:A 14 10 INT conforms conforms 2 1:A 13 8 INT conforms conforms 2 2:A 13 9 -- Local Ints: Type Polarity Trigger Bus ID IRQ APIC ID PIN# NMI conforms conforms 3 0 255 1 ExtINT conforms conforms 3 0 255 0 ------------------------------------------------------------------------------- MP Config Extended Table Entries: -- System Address Space bus ID: 0 address type: memory address address base: 0xa0000 address range: 0x20000 -- System Address Space bus ID: 0 address type: memory address address base: 0xc8000 address range: 0x18000 -- System Address Space bus ID: 0 address type: memory address address base: 0xfc000000 address range: 0x4000000 -- System Address Space bus ID: 2 address type: memory address address base: 0xfa000000 address range: 0x2000000 -- System Address Space bus ID: 0 address type: I/O address address base: 0x0 address range: 0x3b0 -- System Address Space bus ID: 0 address type: I/O address address base: 0x3b0 address range: 0xc -- System Address Space bus ID: 0 address type: I/O address address base: 0x3bc address range: 0x4 -- System Address Space bus ID: 0 address type: I/O address address base: 0x3c0 address range: 0x20 -- System Address Space bus ID: 0 address type: I/O address address base: 0x3e0 address range: 0x1f20 -- System Address Space bus ID: 2 address type: I/O address address base: 0x2300 address range: 0xdd00 -- Bus Heirarchy bus ID: 3 bus info: 0x01 parent bus ID: 0 =============================================================================== ------=_Part_769_12954910.1101814185802 Content-Type: text/plain; name=dmesg-current.txt; charset=us-ascii Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename="dmesg-current.txt" Copyright (c) 1992-2004 The FreeBSD Project.
