Description
The i8042 (PS/2) driver in the current revision (r1382) fails to work properly on the Intel S5000XVNSATAR machine (see Lab). The functionality was probably broken by the recent rewrite of the i8042 from a legacy driver to a DDF driver. The previous legacy i8042 driver worked properly on this machine.
I have encountered and fixed several problems while analysing the problem: The i8042 driver never got started in the first place (fixed in r1376) and the enumeration of input devices failed due to an infinite loop in loc_get_categories() (r1377 - r1380).
Currently, only the first interrupt generated by the i8042 gets delivered to the driver. Connecting an USB keyboard is possible, but sometimes locks up the entire machine (uncertain if this is a related problem).
