I just upgraded my Panasonic Toughbook CF-52 from kernel 2.6.24.4 to 2.6.25. On this notebook I had to exchange the DSDT to get ACPI working, but with this exchange suspend works fine with kernel 2.6.24.4. But now I upgraded to 2.6.25 and used the same DSDT. The system starts without any problems with ACPI enabled. When I close the display, the system goes into suspend mode, as it should. But when I open the display again, the green LED goes on, as if the system tries to start again, but then the system hangs. The display stays dark and it doesn't react to any key-stroke any more. With kernel 2.6.24.4 it just wakes up as it should and I can continue my work from the status, it was before the suspend. Does anyone know something about this bug in kernel 2.6.25?
