Okay, the patch applied easily and the kernel is now compiling. When installed, I'll try and boot it (and will use a PS/2 mouse instead of my current USB mouse, or should I rather try to plug my USB mouse to the ehci_hcd controller ?). How would you like me to boot ? With or without the "usb-handoff" option ? With or without the BIOS "USB mouse support" option ? And once booted, what information will you be interested in ? -- Michel Bouissou OpenPGP ID 0xDDE8AC6E
