Description

Keyboard interrupts are not working on the Acer C710 (PARROT) with the current coreboot revision. On further analysis, the PS/2 controller's status bit indicates that interrupts should be enabled. However, there are no interrupts being received by the OS. Polling the PS/2 data register (0x60) every 10 ms reveals that the keyboard is indeed key scanning and sending data properly, indicating that there is a problem with the interrupt routing.
