To: Linux kernel mailing list Date: Wed, 24 Oct 2001 23:32:45 +0200 (MEST) From: R.E.Wolff@BitWizard.nl (Rogier Wolff) X-Mailer: ELM [version 2.4ME+ PL60 (25)] MIME-Version: 1.0 Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org 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because the kernel is using the APIC to route interrupts, such that my BIOS configuration "used-by-Legacy-ISA" is no longer in effect.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. -- ** R.E.Wolff@BitWizard.nl ** http://www.BitWizard.nl/ ** +31-15-2137555 ** *-- BitWizard writes Linux device drivers for any device you may have! --* * There are old pilots, and there are bold pilots. * There are also old, bald pilots.
