Hi,

Hello duqi,

The dtb is compiled into xen and init ramdisk is bind into the kernel zImage. 
Dom0_mem is configured as 128MB.

Why do you compile the DTB into Xen? I guess you have hardcoded the chosen node... if so can you paste the content here?

we crash message on a page allocation bug.
Here is our message dumped.

I'm suprised that the call trace is so small. Did you copy everything?
