"encrypted.block" mount error in CROS boot process.

[Albert]

I modified CROS's kernel, for general CPUs.

when it boot in 'Intel Core2' PC(Fujitsu), it was fine.

But when it boot in 'Intel Pentium M' PC(IBM), it couldn't boot.

I guess "encrypted.block"(in STATE partition) can't mount by mount-encrypted(/usr/sbin/mount-encrypted, binary file).

"/usr/sbin/mount-encrypted" is called by "/usr/share/cros/startup_utils.sh", and "/usr/share/cros/startup_utils.sh" is called by "/sbin/chromeos_startup"

Below is error log of mount-encrypted in 'Intel Pentium M' PC(IBM).

[pid:266] Starting.

And below is normal log of mount-encrypted in 'Intel Core2' PC(Fujitsu).

What is the problem? Why this happens?

What should I do?
