Issues after starting a RAMdisk on a device with iOS 4.3.4

[GoogleCodeExporter]

Since iOS 4.3.4 my iPhone 4 boots in Recovery Mode after a RAMdisk was started 
on the device. With iOS <= 4.3.3 everything works fine (device boots into 
normal mode).

What steps will reproduce the problem?
1. Install iOS 4.3.4
2. Build RAMdisk with SSH (build_ramdisk.sh)
3. Boot RAMdisk (using tetheredboot)
4. Reboot device (using SSH and "kill 1")

What is the expected output? What do you see instead?
iPhone sould boot into normal mode.
iPhone boots into recovery mode

What version of the product are you using? On what operating system?
iDevice: iPhone 4, Model MC603DN, 16 GB, iOS 4.3.4 (8K2)
RAMdisk: 4.2.1 (), 4.3.3 (), 4.3.4 ()
OS:      Mac OS X (Build RAMdisk) / Windows Vista 32bit (Run tetheredboot)

Please provide any additional information below.
With iOS <=4.3.3 a restart boots the device into normal mode. Anyone with 
simliar issues?
