Not a solution, but I don't believe apic is enabled by default in
the 'stock' kernels. I've only been usin FC5-tx (updated daily) for a
few weeks after movin from Mandriva cooker. Out of curiosity, one'a
the first things I explored was the kernel configs (IE, default
settings) and dmesg boot results.
~ $ kcfg apic
2.6.15-1.1915_FC5
CONFIG_X86_GOOD_APIC=y
CONFIG_X86_UP_APIC=y
CONFIG_X86_UP_IOAPIC=y
CONFIG_X86_UP_APIC_DEFAULT_OFF=y <======
CONFIG_X86_LOCAL_APIC=y
CONFIG_X86_IO_APIC=y
... all previous kernels back to FC5-t2 install were the same. Also
i686, acpi, preempt_voluntary, an 4gb mem addressing default enabled.
Havin used both acpi an apic together for years for IRQ's, I enabled
apic kernel parameter;
~ $ kdmesg apic
2.6.15-1.1915_FC5
