When trying to boot 2.6.30-rc1, -git3 on my notebook, which
has an encrypted root partition (LUKS/dmcrypt), the root fs can
not be found any more.

The bootscreen finally shows:
[....]
Could not find /dev/mapper/root
...exiting to /bin/sh

And the system is dead. Since there's no root fs available, I can't provide
any more information on this.

BUT: Ingo's reversion does fix this.

Regards,
Heinz.
