Yeah you are right, its a BIOS issue. I tried to find out how the OS is
informed about the device taken away. But none of the hotplug
drivers or enabling acpi debug showed anything here. I wonder how this
is done in the "other" operating system. Or how the device could be
re-enabled, plugging the wires back doesn't help. Very weird.
Anyway, I found a BIOS option to disable this behavior and now things
work unpatched. Thanks for your help.
Joerg
