Bug#854231: Fwd: Re: Fwd: Kernel 4.9 traces

[Wolfgang Schnitker <wolfgang.schnitker@gmx.de>]

Additional information:

Just checked this:

setserial -g /dev/ttyS*

/dev/ttyS0, UART: unknown, Port: 0x03f8, IRQ: 4
/dev/ttyS1, UART: 16550A, Port: 0xcc00, IRQ: 17
/dev/ttyS2, UART: 16550A, Port: 0xc880, IRQ: 17
/dev/ttyS3, UART: 16550A, Port: 0x02e8, IRQ: 3

Are we opening a non exsisting port?

Did an update-initrd for all kernels, reboot, errors while booting are gone.

But still have 4 ttyS with only 3 physical ports.

sudo dmesg| grep tty
