Could kernel support kexec on PPC64(e6500)?

[liu.song11 at zte.com.cn]

Hi,

My board is PPC64(e6500 series).When I use kexec-tools, I do the following operations,
then the kernel panic.

1. ./kexec -l ./vmlinux --initrd=/ramdisk.bin    (segments load right)
2. ./kexec -e

Then the kernel panic in kexec_sequence. I check NIP is point at mtmsrd r3,1
which in kexec_sequence（misc_64.S）. I have no idea on this fault, and need
some help.

Regards
