Yep, definitely time to blow some dust off various old tomes :)
Between 7.x and 8.x the default serial driver changed from sio to uart.
You can recompile your kernel and get sio back and see if that has an effect.
Actually I see you used cuaU0 - that is a USB serial dongle so the driver change would have no effect.
That said the stack was rewritten between 7 & 8 too so perhaps that is related.
