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.

ok great, thanks for your feedback.
2.6.8 is heavily stabilized for the upcoming release,
there will be no hassle of a big acpi backport.
debians 2.6.8 is only left open for security updates,
that are currently on the way.
