we have a PC Engines APU. This PC has only a Serial-Console.
After the upgrade from buster to bullseye I see the kernel output on
ttyS0 but there is no keyboard input available, neither in Grub.
Getty is startet on ttyS0, I see a login prompt.
Did anyone has had a similar problem?
Yourself, perhaps. Is this the machine that required
usbserial_pl2303.mod in Grub's core image? How did

has it been overwritten?
