No, no change to consoles, but I'll double check it.

I am sure I did not make any changes to bootloader on the device, no
change to kernel, no change to console setup, the only changes were
applications, which are nothing to do with this problem. Having said
that, I'll double check it.

I am not too concern about different message, but it looks like a
different system to start Bluetooth, ALSA, can, NFS, videodev, vgaar
which was weird, that device does not have sound, video, and
bluetooth. But the real problem I posted here is after 2 - 3 good
boot, the boot failed with so many errors of Failed to start udev
Coldplug all Devices, Failed to mount FUSE Control File System, Failed
to start Remount Root and Kernel File System, it seems it was
completed damaged by something which I found no clue for it.

Let me clarify it again, when I test the boot, I just switch it on,
shut it down, turn it on again several times, no thing injected to the
bootload or kernel, no thing was deleted. Has anyone seen that
problem? Appreciate if you could explain what could cause that errors?

Thank you very much.

Kind regards,
