Dear Gregory CLEMENT,

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.

Hi Thomas, Gregory

So, twenty reboots later, no problems at all with 3.8-rc2. Got to
user space every time.

So, what are we doing differently?

BootROM 1.15
Booting from NOR flash
DDR3 Training Sequence - Ver 2.5.DDR3 Training Sequence - Registered DIMM WL -  
BootROM: Image checksum verification PASSED
 ** LOADER **


U-Boot 2009.08 (Jul 27 2012 - 18:23:11)
Plat'Home version: 1.1.1 (Base: Marvell BSP  2.2.3 NQ)

Do you have the same version?

I'm tftpbooting:

setenv bootargs root=/dev/ram console=ttyS0,115200 earlyprintk ; tftpboot 0x80000000 openblocks-dev; bootm

My image contain the kernel and a buildroot rootfs included within the
kernel image and DT is appended. I load it to address 0x80000000,
which puts it at the beginning of CS 3:

DRAM:   3 GB
       CS 0: base 0x00000000 size  1 GB
       CS 2: base 0x40000000 size  1 GB
       CS 3: base 0x80000000 size  1 GB

Thanks
