The first thing would be to define what you refer to with the term "wacky" :)

Does it fail creating the controls? Don't the control do what they're
supposed to? Is the behaviour deterministic?

An easy way to track things in the driver is to add
printk(KERN_WARNING ...); lines in the driver, then compile, unloaded
and load the module again. Then find these lines in your syslog.
