First, thanks for your prompt answer.

Yes, I noticed that.

Yes. Seems like your modules are more mature than those of the current release

In fact, it DOES solve the problem! Such a simple solution!
I added this command to my rc.local_shutdown script and tested it, and it
works perfectly. It unloads all the modules and kills all the processes using
these modules, thus resolving the hardware resource conflict.

From the warnings during boot and from the dmesg message.
I got this:
PCI quirk: region 1000-107f claimed by ICH6 ACPI/GPIO/TCO
and theb this:
ACPI: PCI Interrupt Link [LNKF] (IRQs 11) *0, disabled.
I do not know for sure it is related to the IRQ conflict, but I suspect it is
so, since I found similar reports on the net and they all blamed it on the
IRQ handling by APIC.
Anyhow, thanks for the help!
