I am unable to use the 2.4.19-pre*|rc* series of kernels if
CONFIG_X86_UP_IOAPIC is enabled for the kernel compile. The dmesg log
file tells me to email you about the problem, so here it is! The basic
system components are:
motherboard: LeadTek Research Winfast 7350KDA (based on the SiS 735 chipset)
BIOS: Award Modular Bios v6.00PG
BIOS id: 02/01/2002-SiS-735-7350KDA.C-00
CPU: Athlon XP 1700+
I have attached the following files:
dmesg-IOApic - the dmesg log file when booting a kernel with IO-APIC
enabled
lspci-wo-apic - the output of 'lspci -v -v' when booting a kernel w/o
IO-APIC enabled
lspci-w-apic - the output of 'lspci -v -v' when booting a kernel with
IO-APIC enabled
interrupts-wo-apic - the contents of /proc/interrupts when booting a
kernel w/o IO-APIC enabled.
interrupts-w-apic - the contents of /proc/interrupts when booting a
kernel with IO-APIC enabled.
config - the .config file used for compiling the kernel
I am also getting a strange error message displayed on the console,
which may be related to this situation:
spurious 8259A interrupt: IRQ7.
This occurs even when I run a non IO-APIC enabled kernel.
Also note that while I am using the -ac kernel patches (because of their
support for the SiS 5513 chipset), the same thing occurs with the plain
-rc series.
Thanks very much. By all means let me know if I can be of any further
assistance.
