Why am I (only, seems) always answering NON YOCTO issues in the YOCTO
thread??? ;-)

OK. The good sign about what U R talking is shown here:
[    0.000885] printk: console [tty1] enabled

It is on the several places:
[    6.480654] ttyS ttyS0: 2 input overrun(s)
[    7.962826] smsc95xx 1-1.1:1.0 eth0: link up, 100Mbps, full-duplex,
lpa 0xCDE1
[    7.973416] ttyS ttyS0: 2 input overrun(s)
[   11.883822] Installing knfsd (copyright (C) 1996 [email protected]).
[   11.893705] ttyS ttyS0: 2 input overrun(s)
[   13.268076] NFSD: Using /var/lib/nfs/v4recovery as the NFSv4 state
recovery directory
[   13.280639] ttyS ttyS0: 2 input overrun(s)

It seems that the solution for this problem is:
https://www.linuxquestions.org/questions/linux-kernel-70/tty-usb-input-overruns-4175512707/

Namely:

Please, let us know.
