-My machine
(kernel 2.4.21) hung
after printing this. (
Athlon 2000 XP
on an AD77 motherboard (KT400)). It is caused by [APIC] support in the kernel. Booting with the "noapic" kernel flag didn
't fix it (although it made
the machine go into an infinite loop printing an error about apic on cpu ). Recompiling the kernel without APIC support resolved
this.
+Various VIA chipset AMD Athlon/Duron motherboards
(eg KT400, KM266) running kernel 2.4 (e.g.
kernel 2.4.21) hang
after printing this message
. For example,
Athlon XP2000+
on an AD77 motherboard (KT400), Athlon XP1800+/XP2400+ on a PC Chips M825L (KM266
)). It is caused by [APIC] support in the kernel (not to be confused with "ACPI")
. Booting with the "noapic" kernel flag doesn
't fix it (although it can make
the machine go into an infinite loop printing an error about apic on cpu ). However, booting with "no__l__apic" kernel flag does in many cases work
. Recompiling the kernel without APIC support resolves
this. Note that the same motherboards will need the "nolapic" kernel flag to boot Knoppix - otherwise the screen just turns black and the pc hangs.

+This is usually caused by a failure to find or mount /dev or a bad /dev being used. When remastering [Knoppix] this can be cause by failing to preserve the special nature of the device files under /dev while building remastering. See the "dev" option of the mount(8)
