Package: kernel-image-2.6.8
Version: 2.6.9-3
Severity: serious

This problem was reported to debian-deval and debian-kernel in November
last year. 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.

The main problem is that alsa does not work.
