Ole, is it losing interrupts or is it completely dead? I know that serio only has knowledge of the generic i8042 device; in most cases it doesn't know a lot about initializing multi-function controller chips, such as the Winbond. The Winbond documentation is a little obscure on this subject - OK, a lot obscure - depending on which chip docs you look at, it only lists the register maps and doesn't describe the I/O port accesses needed to set the registers. However, if you look at parport_pc.c, you can see how to access the registers. In any case, psmouse is just a shim between input and serio, not the driver itself, so as you have seen, reloading it doesn't help in most cases. ------------------------------------------------------- SF.Net email is sponsored by Shop4tech.com-Lowest price on Blank Media 100pk Sonic DVD-R 4x for only $29 -100pk Sonic DVD+R for only $33 Save 50% off Retail on Ink & Toner - Free Shipping and Free Gift. http://www.shop4tech.com/z/Inkjet_Cartridges/9_108_r285
