[Buildroot] No response after "Freeing init memory"

Tue Feb 22 08:06:34 UTC 2011

Hello!

Marek: I added user_debug=31 to kernel command line, but I think it doesn't
show any problem. Not very long so I copy it directly into e-mail.

Charles: generic console support is set to ttyS0 and correct speed (115200).
I have default inittab. I'm not very experienced in configuring inittab, but
at first look there is nothing weird.

Daniel: line ::respawn:-/bin/sh was added to /etc/inittab and it's same -
after Freeing ... is only silence.

Buildroot and kernel configs are here:
http://sestka.zlutaponorka.com/zd/configs.zip.

Best regards,
Zdenek Materna
