Message-ID: <20020607131626.S33468-100000@snail.stack.nl> MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Hi, This is an old one: been there since early 2.5. The IRQ remapping table generated by my BIOS is taken over by the APIC, but (afaics) not by the pci data structures. Result: Drivers claim the wrong IRQ line (as can be seen in /proc/interrupts). No sound, not network, no SCSI, which means: no root filesystem and thus no boot :( At the moment I "fix" this by telling the kernel to ignore the APIC, this is not the preferred way to go imho. I also reported this somehwere around kernel 2.5.8 or something, got the answer this was a know bug that was about to be fixed, but so far, no improvement. If it does matter: I got an Intel LX-chipset based SMP system. Jos
