| The following are some symptoms which may indicate an IRQ-related problem: * Hardware devices being detected, but not functional (sound, network, etc.) * Problems using two hardware devices at the same time, or only when devices are connected at the same time * System hangs If you think you may be experiencing such a problem, try these steps in order: * Boot the system with the `noapic` boot parameter * Boot the system with the `nolapic` boot parameter * Boot the system with the `pci=noacpi` boot parameter * Boot the system with the `acpi=off` boot parameter If you are experiencing system panics or hangs, follow the instructions at DebuggingSystemCrash From AnthonyBarker Tue Feb 22 04:37:37 +0000 2005 From: Anthony Barker Date: Tue, 22 Feb 2005 04:37:37 +0000 Subject: Check the Bios or change items Message-ID: <20050222043737+0000@https://www.ubuntulinux.org> 1) If you have a Bios conflict also ensure you check your bios to see if some of the items can be turned off temporarily (serial ports etc). 2) Try changing the order of the cards in your pc. I've seen it where due to bios issues cards work in certain slots and not in others. CategoryDocumentation CategoryCleanup |
