Reboots on Serial read: Use Fuse L:0xf7

[zevero]

I lost a day, because I experienced frequent resets on serial reads.
This did not occur on the pins of Serial1 only on Serial and EVEN on an empty sketch without Serial.begin just with a short blink on a led in setup() to indicate the reboot.

Well the solution was for me to use Low fuse 0xf7 instead of 0xff.

Please add a footnote somewhere, since I think that many will run into this issue!
I myself tested it with 3 different setups and Atmega1284p .... and I am still not sure, why this occured...
