Hello, 
  I was trying kexec in sh3 (HP jornada 660lx:
SH7709 - HD64461) using those kexec-tools. But it gets
frozen when run "kexec -e". I would wish to know
what might be the issue.

Also, I used strace with "kexec -e" to see the last
reboot system call:

root@jornada6xx:~$ kexec -l /boot/zImage
--append="root=/dev/sda1 mem=32M"
root@jornada6xx:~$
root@jornada6xx:~$ kexec -f
kexec 1.101 released 15 February 2005
...
ADDRESS of empty_zero can be set SHELL environment
variable
KEXEC_EMPTY_ZERO as default
...
ADDRESS can be get in the following method in your
system.
..
3) CONFIG_MEMORY_START + CONFIG_ZERO_PAGE_OFFSET in
your kernel config file.
root@jornada6xx:~$


Well, The kernel (2.6.23-rc5 from jlime) was built
with 
CONFIG_MEMORY_START=0x0d000000
CONFIG_ZERO_PAGE_OFFSET=0x00001000
in the .config file. So i did:


root@jornada6xx:~$ export KEXEC_EMPTY_ZERO=0x0d001000
root@jornada6xx:~$ strace kexec -e
...
reboot(LINUX_REBOOT_MAGIC1, LINUX_REBOOT_MAGIC2,
0x45584543 /* LINUX_REBOOT_CMD_
??? */Starting new kernel
kexec information
  segment[0]: 0x0c001000 - 0x0c002000 (0x00001000)
  segment[1]: 0x0c210000 - 0x0c3b8000 (0x001a8000)
  start     : 0x8c210000

nothing else happened.

Regards,
Rafael
