Please verify that the patch is applied and working by excluding acpi_dbg_level=1 from the cmdline and verifying that you get some new "NOT disabled" lines in the dmesg.
Please restore the IOAPIC support so we get the print_PIC lines back per the original debug patch, and boot with "nolapic" "apic=debug" "pci=routeirq" and send along the dmesg. This will tell us about the state of IRQ6 when we get it from the BIOS and how Linux changes it.
Also, if you can send or point me the output from acpidmp, available in /usr/sbin or in pmtools: http://ftp.kernel.org/pub/linux/kernel/people/lenb/acpi/utils/ I'd like to examine the ASL associated with the interrupt link that is camped on IRQ6.
thanks, -Len
ps. In addition to soft-power-off, I expect that ACPI is required to enable IOAPIC support on this system.
