I ha= ve a hang problem on my board based on MPC8377EWLAN, here is how i ran into= problem. We are using u-boot to load the kernel, rootfs and device tree.&n= bsp; The kernel parameters have been set

root= =3D/dev/ram rw rootfstype=3Dext2 ramdisk_size=3D131322 console=3DttyS0,1152= 00

but I load the rootfs image generated of rootfs= .jffs2 (we use buildroot), which results in kernel spitting the following m= essage and hang. I even enabled the WDT (mpc83xx_wdt.c) the board doe= s not get reset.

Any ideas would be appreciated.

Thanks
