Test programs that use shell and have stdio_cdc_acm enabled show corruption of the first input to shell. So far I have just seen this on my sodaq-sara-sff boards, but I assume this is true for all sam0 (arduino style boards).
Steps to reproduce the issue
build one of the test programs
connect a "term"
look at the output
type help and ENTER
Expected results
The banner should be printed, the test program's introduction and a prompt.
Actual results
With make ... term you'd see something like this:
$ make CC_NOCOLOR=1 BOARD=sodaq-sara-sff -C tests/periph/gpio flash term
make: Entering directory '/home/kees/src/RIOT/tests/periph/gpio'
Building application "tests_gpio" for "sodaq-sara-sff" with MCU "samd21".
