Hi,

I am trying to get a 2.6.27.6 kernel to boot on an MPC8568E processor.  The kernel/patches/compiler came from Freescale's LTIB release in December 2008.  Using the same kernel source, toolchain, and ramdisk image, I can boot and run an SMP kernel on the MPC8572E processor which is on the same board.  This is what I see on the 8568E processor:

...
brd: module loaded
loop: module loaded
fsl_pm.ko: loading ...
fsl_pm.ko: no SoC node, ignoring
fsl_pm.ko: hal initialisation
Gianfar MII Bus: probed
eth0: Gianfar Ethernet Controller Version 1.4-skbr1.1.4, 00:80:4d:22:00:66
eth0: MTU = 1500 (frame size=1524, truesize=1800)
eth0: Running with NAPI enabled
eth0: 128/128 RX/TX BD ring size
eth1: Gianfar Ethernet Controller Version 1.4-skbr1.1.4, 00:80:4d:22:40:66

mice: PS/2 mouse device common for all mice
i2c /dev entries driver
EDAC MC: Ver: 2.1.0 Feb  9 2009
TCP cubic registered
NET: Registered protocol family 17
RPC: Registered udp transport module.
RPC: Registered tcp transport module.
RAMDISK: Compressed image found at block 0
VFS: Mounted root (ext2 filesystem).
Freeing unused kernel memory: 144k init
Bad trap at PC: 100b7354, SR: 2d000, vector=2020
init has generated signal 5 but has no handler for it
Kernel panic - not syncing: Attempted to kill init!
Rebooting in 180 seconds..

I am not using a debugger, so I can't see where the SIGTRAP would be coming from.

Thanks in advance,

Scott
