There are some important parts of my config : CONFIG_MPENTIUM4=y CONFIG_X86_CMPXCHG=y CONFIG_X86_XADD=y CONFIG_X86_L1_CACHE_SHIFT=7 CONFIG_RWSEM_XCHGADD_ALGORITHM=y CONFIG_X86_WP_WORKS_OK=y CONFIG_X86_INVLPG=y CONFIG_X86_BSWAP=y CONFIG_X86_POPAD_OK=y CONFIG_X86_GOOD_APIC=y CONFIG_X86_INTEL_USERCOPY=y CONFIG_X86_USE_PPRO_CHECKSUM=y CONFIG_HPET_TIMER=y # CONFIG_HPET_EMULATE_RTC is not set # CONFIG_SMP is not set CONFIG_PREEMPT=y CONFIG_X86_UP_APIC=y CONFIG_X86_UP_IOAPIC=y CONFIG_X86_LOCAL_APIC=y CONFIG_X86_IO_APIC=y CONFIG_X86_TSC=y CONFIG_X86_MCE=y CONFIG_X86_MCE_NONFATAL=y CONFIG_X86_MCE_P4THERMAL=y # CONFIG_TOSHIBA is not set # CONFIG_I8K is not set CONFIG_MICROCODE=y CONFIG_X86_MSR=m CONFIG_X86_CPUID=m # CONFIG_EDD is not set CONFIG_NOHIGHMEM=y # CONFIG_HIGHMEM4G is not set # CONFIG_HIGHMEM64G is not set # CONFIG_MATH_EMULATION is not set CONFIG_MTRR=y # CONFIG_EFI is not set CONFIG_HAVE_DEC_LOCK=y
# # Power management options (ACPI, APM) # CONFIG_PM=y # CONFIG_SOFTWARE_SUSPEND is not set # CONFIG_PM_DISK is not set
# # ACPI (Advanced Configuration and Power Interface) Support # CONFIG_ACPI=y CONFIG_ACPI_BOOT=y CONFIG_ACPI_INTERPRETER=y # CONFIG_ACPI_SLEEP is not set # CONFIG_ACPI_AC is not set # CONFIG_ACPI_BATTERY is not set # CONFIG_ACPI_BUTTON is not set # CONFIG_ACPI_FAN is not set # CONFIG_ACPI_PROCESSOR is not set # CONFIG_ACPI_ASUS is not set # CONFIG_ACPI_TOSHIBA is not set # CONFIG_ACPI_DEBUG is not set CONFIG_ACPI_BUS=y CONFIG_ACPI_EC=y CONFIG_ACPI_POWER=y CONFIG_ACPI_PCI=y CONFIG_ACPI_SYSTEM=y # CONFIG_ACPI_RELAXED_AML is not set
# # APM (Advanced Power Management) BIOS Support # # CONFIG_APM is not set
# # CPU Frequency scaling # # CONFIG_CPU_FREQ is not set
So preempt yes, SMP no.
And there is quite interesting (for me) part of dmesg :
00000030000000 (ACPI NVS) 767MB LOWMEM available. found SMP MP-table at 000ff780 hm, page 000ff000 reserved twice. hm, page 00100000 reserved twice. hm, page 000fd000 reserved twice. hm, page 000fe000 reserved twice. On node 0 totalpages: 196416 DMA zone: 4096 pages, LIFO batch:1 Normal zone: 192320 pages, LIFO batch:16 HighMem zone: 0 pages, LIFO batch:1 DMI 2.3 present. I had the same problem (if it is problem :-) also with 2.4 I don't know if it is problem because "everything" works fine, but maybe it will help you(me :-). David
