Hello, I made some progress here. After playing with BIOS settings, i am now able to: - Boot with ACPI enable (shutdown -p works as expected now); - Use USB devices. In order to do that, i had to totally disable "APIC Function" in the BIOS. With "APIC Function" enabled, neither version 1.4 nor 1.1 of the "MPS Table Version" settings solved my problem. So, although i meed to disable "APIC Function", all seems to works correctly together: ACPI support and USB support. As a side note, i did not encountered anymore the interrupt storm on the uhci USB host controller driver. Maybe can someone explain me what may be wrong with "APIC Function", and if there is some drawbacks to disable it (or what is the purpose of this setting)? -- -jpeg.
