Hi, thanks!

It seems a bit strange that checkroot gave no output, just failure -
as if it's execution didn't even started, and, since it's one of the
first initscripts to start, prehaps there's a problem with bash
interpreter or access to init.d path.

Since you've mounted filesystem and it looks okay, you can try changing
last two columns in /etc/fstab for root filesystem to "0 0", so script
won't try to check it - that way you can see if it's something with
fsck - prehaps the system will just boot.

I have tried it, but nothing change.

Then, if the rest of the initscripts won't throw some similar errors
(possibly exposing the real problem), you can probably insert a lot of
echoes/einfos to that initscript to see at which point everything hangs
and check what's wrong with the command causing it.

I have inserted some echos, now the "checkroot" script is:
