From: Klaus Kudielka At least on x86_64 the present cyclades.h is broken due to the wrong size of uclong. This affects, of course, both the kernel and the user-level utilities. The symptom is that cyzload refuses to load the firmware. I also managed to freeze the machine when unloading the module. The patch below fixes this in an architecture-independent way. I have tested it with 2.6.19 and the driver works fine again with a Cyclades-Z on an Athlon 64 X2.
