Package: kernel-image-2.6.8-1-686 Version: 2.6.8-10 Severity: serious This problem was reported to debian-deval and debian-kernel in November last year already. The net effect of failure to allocate IRQ 7 for ALSA is that it fails to start. The problems can be overcome by adding append="pci=acpi" or append="acpi=noirq" to lilo.conf. But, as these are workarounds, the cause should be corrected. I'll file a bug report on this if noone have an immediate solution? The problems heve been found for at least kernels 2.6.8 and 2.6.9. Maybe the BIOS has to be upgraded and/or there is something wrong with the PCI routing tables.
