Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII; format=flowed Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Context: IBM X20 laptop with integrated PCI CS4281 soundcard. Loading snd_cs4281 gives these messages and registers no alsa device: ACPI: PCI interrupt for device 0000:00:0b.0 disabled CS4281: probe of 0000:00:0b.0 failed with error -5 Error -5 seems to be -EIO. There is no option ib bios to enable/disable the soundcard and the bios is almost the latest (2.23, latest 2.25 fixes only unrelated things by changelog). lspci identifies the card as follows (pci ID is the same as in the driver): 0000:00:0b.0 Multimedia audio controller: Cirrus Logic Crystal CS4281 PCI Audio (rev 01) I tried pci=routeirq. It distributed the interrupts differently but this problem did remain. I tried acpi=ogg and the ACPI line disappeared but probe failure stayed. So how can I enable the soundcard? -- Meelis Roos (mroos@linux.ee)
