You don't use PS/2 mouse and so BIOS told us that mouse is absent and reassigned IRQ12 to EHCI controller. However we do not listen to BIOS on i386 (for historucal reasons) and process with registering AUX port... Now IRQ12 is shared between AUX port and EHCI and the keyboard controller is unhappy wehereas before (with polling timer) it would release IRQ12 and close port... Does your keyboard start working if you boot with i8042.noaux? -- Dmitry - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
