Ah right, that explains :) The find must be for ttyS* in this case, here's the diff for qemu x86 for command: # find /sys -name ttyS* --- /tmp/before 2023-10-25 10:50:29.870083012 +0300 +++ /tmp/after 2023-10-25 10:52:52.770393075 +0300 @@ -3,7 +3,7 @@ /sys/class/tty/ttyS0 /sys/class/tty/ttyS3 /sys/class/tty/ttyS1 -/sys/devices/pnp0/00:04/tty/ttyS0 -/sys/devices/platform/serial8250/tty/ttyS2 -/sys/devices/platform/serial8250/tty/ttyS3 -/sys/devices/platform/serial8250/tty/ttyS1 +/sys/devices/pnp0/00:04/00:04:0/00:04:0.0/tty/ttyS0 +/sys/devices/platform/serial8250/serial8250:0/serial8250:0.3/tty/ttyS3 +/sys/devices/platform/serial8250/serial8250:0/serial8250:0.1/tty/ttyS1 +/sys/devices/platform/serial8250/serial8250:0/serial8250:0.2/tty/ttyS2 > And can you post the equivalent diff for serdev as well for completeness?

OK makes sense. Thanks, Tony
