Jean-Baptiste, Thank you for your contribution here - you've found appropriate workaround for a IRQ routing bug (in the BIOS?). I suspect this is an ACPI issue and not a kernel issue, mainly because the kernel is trying to follow the settings as defined in the BIOS and hence it can only do what it is told. We could put a lot of effort here to probably find there is no kernel bug, but a ACPI misconfiguration. If one is feeling adventurous enough, the final step is to find out the buggy settings and override them with a new DSTD (links have been supplied above in one of my postings on the steps required).
I will mark this this as "Won't Fix" tomorrow as I am confident this is not a kernel issue. If you think this is unsatisfactory, please let me know and we can discuss what to do next.
