Is there any way to manually disable the IO-APIC support in the kernel?
I just installed Mandrake 7.0. When it try to boot I get a kernel panic.
Goes something like this:
calibrating APIC timer ...
..... CPU clock speed is 165.9173 MHz.
..... system bus clock speed is 0.0000 MHz.
Booting process 1 eip 2000
APIC never delivered???
APIC delivery error (ef).
CPU #1 not responding. Removing from cpu_online_map.
Booting processor 15 eip 2000
Not responding.
Total of 2 processors activated (66.15 BogoMIPS).
enabling symmetric IO mode... ...done.
ENABLING IO-APIC IRQs
init IO_APIC IRQs
IO-APIC (apicid-pin) 2-0, 2-20, 2-21, 2-22, 2-23 not connected.
..MP-BIOS bug: 8254 timer not connected to IO-APIC
...trying to set up timer as ExtINT... .. (found pin 0) ... failed.
...trying to set up timer as BP IRQ... failed.
Kernel panic: IO-APIC + timer dosen't work!
In swapper task - not syncing
The "linux-up" kernel that Mandrake built works just fine as it dosen't
appear to try to use the APIC. (atleast cat /proc/interrupts shows all XT
PIC). So how can I disable support for the APIC in a custom kernel I build?
