Hello I'm experiencing some trouble with interupts being lost from my cdrom while trying to rip audio cd. I notced my motherboard is using APIC mode in bios and my kernel (on suse 8.2) was initialy installed with CONFIG_X86_UP_APIC=y CONFIG_X86_UP_IOAPIC=y I would like to disable APIC (also change to PIC in BIOS) in linux and see if it has anything to do with lost interupts.. Is it possible without kernel recompilation? Linux 2.4.20-4GB-athlon #1 Mon Mar 17 17:56:47 UTC 2003 i686 regards, himba -- This €-mail was Kmailed.

On your kernel line in /boot/grub/menu.lst, add the parm 'noapic'. That's all it takes. See the 'failsafe' entry for an example.

It's documented many places, but quoting Mr Philipp from this list - this is probably in the FAQ, I haven't checked lately:
See http://sdb.suse.de/en/sdb/html/81_acpi.html for the possible acpi options and http://www.suse.de/en/private/products/suse_linux/i386/acpi.html for more background.
(note that acpi has more to do with interrupts than apic, but the two are very much related) -- Cheers, Carlos Robinson
