Summary: Nvidia Nforce2 interrupt handling problems Kernel Version: 2.6.0-test1 Status: NEW Severity: normal Owner: greg@kroah.com Submitter: andy-kernel.388488@dustman.net
Distribution: Gentoo
Hardware Environment: Athlon-XP, Nvidia Nforce2 chipset, Radeon 8500 (r200) AGP, 3com 3c920
Software Environment: AWARD BIOS gcc version 3.2.3 20030422 (Gentoo Linux 1.4 3.2.3-r1, propolice) GNU ld version 2.14.90.0.2 20030515 <-- binutils XFree-4.3.0
Problem Description:
PCI interrupt assignments get weird. With certain boot parameters, you can get from mostly non-functional to mostly functional. dmesg from several combinations of parmeters will be attached, but in a nutshell, with local APIC and IO-APIC and ACPI enabled in the kernel, a lot of strange things happen, even if you use noapic and pci=noacpi. Disabling the APIC helps a little, but to be functional at all, pci=noacpi must be used.
Steps to reproduce:
Will be detailed in the following attachments.
