My system is: ASUS L3800C notebook, P4-M (no HT), i845M chipset. I wasn't really sure whether the system had any APIC whatsoever, because every time I tried to compile in APIC support, it backed out with No local APIC found. Note: ACPI without APIC works fine. I compiled 2.5.74 with: CONFIG_X86_UP_APIC=y CONFIG_X86_UP_IOAPIC=y CONFIG_X86_LOCAL_APIC=y CONFIG_X86_IO_APIC=y The system booted well, until Executing all Device _STA and_INI methods appeared, and it seemed to hang in the middle of doing that (SysRq not responding). Running the same kernel with acpi=off works fine whatsoever and produces the following lines: Local APIC disabled by BIOS -- reenabling. Found and enabled local APIC! [...] enabled ExtINT on CPU#0 ESR value before enabling vector: 00000000 ESR value after enabling vector: 00000000 Using local APIC timer interrupts. calibrating APIC timer ... ..... CPU clock speed is 1699.0776 MHz. ..... host bus clock speed is 99.0986 MHz. It's not that I need APIC anyway, but I figured it may be worth reporting.
