Subject: APIC and "ISA" interrupts.
Date: Wed, 24 Oct 2001 23:32:45 +0200 (MEST) [thread overview]
Message-ID: <200110242132.XAA03501@cave.bitwizard.nl> (raw)
After upgrading our fileserver to 2.4, I can't seem to get the ISDN
card to work. I think that's because the kernel is using the APIC to
route interrupts, such that my BIOS configuration "used-by-Legacy-ISA"
is no longer in effect.
I tried disabling the APIC with the following results:
Local APIC disabled by BIOS -- reenabling.
Found and enabled local APIC!
Kernel command line: auto BOOT_IMAGE=linux ro root=302 BOOT_FILE=/boot/vmlinuz disableapic
as far as I can see, the code to print "local apci disabled by bios"
is not called if "disableapic" is on the commandline.
This is linux-2.4.10 that I got with SuSE 7.3
Roger.
