It turns out that the code which enables specific LDN is somewhat buggy.
Instead of enable the device the device gets disabled. However after some time the serial line gets back, most likely some "enable resources" might fix it.
I'm attaching patch which somewhat fixes the problem and changes the function to look same in all superio code. Some boards even did not convert the dev->enabled to 0,1 values.
