Until now I didn't notice any problem on this board with the 3GB enable.

I made more tests since I received this email, I booted (cold and hot boot)
the board dozens of times, and indeed every 5 or 10 reboot the kernel hanged
during boot at line:
"UDP-Lite hash table entries: 512 (order: 2, 16384 bytes)"

I think it hangs at the same place here.

After applying your patch, I didn't notice any hang after 20 boots. Do you
have a test pattern which make the kernel to hang each time to be sure that
it is the root of the problem?

No, I don't have a specific pattern. It just hangs from time to time.
Maybe 1 boot out of 5 or something like that. And it just hangs like it
did for you.

Hi Thomas, Gregory

I've been testing my board some more, using the PlatHome kernel
installed on the device as i received it. I've rebooted the device 20
times and not had a single problem.

I will now swap to a mainline kernel, 3.8-rc2 plus UART patch.
