I needed sound to work so I went to compile sound into the kernel, but
I cannot a compiled-kernel to boot. I seem to only be able to get the
slackware kernel 2.4.22 to boot (but my sound card isnt compiled into
it).

When I compile the kernel and boot, it hangs at this error:
ESR value before enabling vector: 00000002

I did some research and found that it has something to do with booting
or not booting with APIC?

Someone suggested booting with the boot option of 'noapic' ... does
anybody know how to supply this option?

They also said that if that doesnt work to disable CONFIG_*_APIC in
the config. However, I noticed that CONFIG_*_APIC has been set to 'n'
(disabled) all along?

Any information would be greatly appreciated!
Thanks,
Clint

me too

correct
your via-chipset has some bugs that make the APIC code in the kernel go crazy

what bootloader do you use?

if you use grub, just edit /boot/grub/grub.conf or /boot/grub/menu.lst
and add "noapic" to the line that says
"kernel /blablabla root=/dev/hdxx ro" or something similar

i don't know how to do this with lilo

that did work for me
this is the first time i see someone reporting it doesn't work for him
are you sure you aren't doing nothing wrong?

Hi there,

Ok, So i configured lilo to give the kernel the boot param of 'noapic'
but still no-go. I dont know if there is away to check if lilo
actually gave the kernel that boot param, but it says it should have
(according to liloconfig and /etc/lilo.conf).

Any other suggestions?

Thanks for your help!

What motherbaord do you have?

if it's an ECS K7VMM it's normal that the noapic option doesn't work
for this mobo, there is no way to boot with the noapic option, nor to disable
the APIC in the BIOS
if it's another one, try to disable the APIC in your BIOS

BTW, i still think that there's something wrong with your kernel configuration
are you completely sure you have disabled the APIC in the kernel config?
(the setting is in "processor type and features --> Local apic suppurt on
uniprocessors")

Ok, It now works! I was just looking for things that were set to 'y'
that said APIC, but they were worded weird in that section of the
config, so i just pretty much said 'n' to all that power mgmnt stuff
and now it boots just fine

People with VIA chipset motherboards have this problem .. is it not a
good idea to have a VIA motherboard if you know your going to run
Linux on it?
