Subject: Kernel panic: kernel access of bad area pc

I have a process to create tape boot images by combining the kernel and initrd 
into a zImage. The process works for 2.4 (RHEL 3.3) & 2.6 kernels (SLES9 & 
RHEL4). However on SLES8 ppc64 the kernel panics with "error kernel access of 
bad area pc". 

Attached is the complete log of the boot with backtrace data.

The system is:

IBM 7044-170
SLES 8 (2.4.19-ul1-ppc64-SMP)

The kernel was uncompressed using:
# objcopy -j .kernel:vmlinux -O binary vmlinuz vmlinux-storix.gz
# gunzip vmlinux-storix.gz

Which gives me vmlinux-storix

Kernel Memsize
# nm -n /boot/vmlinux-storix | tail -n1
c0000000007c4000 A _end

Anyone have an idea what is causing the failure? The error message appears to 
be pretty generic.
