[solved[KERNEL PANIC ARCH-3.4.4-2] can not boot Arch from liveCD (x64)

i have somes problems with several apps and want to fresh installed Arch.
my current file system:
i use: gpt, lvm2, luks, grub2.
/dev/sda1: bios partition
/dev/sda2: boot partition
/dev/sda3: lvm partition (var, usr, usr-local,....home...)
i keep partition structure (cause i want to keep home directory without damage, it's contain my data).

but when i try to boot from livecd to reinstall Arch, this proccess can't be done.
this is output:

.....
mounting: /bootmnt/arch/any/repo-core-any-sys/....
mounting: /bootmnt/arch/x64/.....
....
I/O error on device sr0, logical block
buffer I/O error on device sr0, logical block
...
SQUASHFS error: .....
end_request: I/O error, device sr0, sector ....
...
kernel panic_not syncing: attempted to kill init !
pid: 1 comm: init Not tainted 3.0 - ARCH #1
call trace:

[<fffffffffffffffff...............] do_exit ...
[.....................................] do_group_exit ...
[.....................................] get_signal_to_diver....
.......

and caps lock  & scroll lock blink.

any ideas?

thanks for reply !

EDIT: i tested /dev/sr0 and the result:

sudo mount /dev/sr0 /mnt
mount: /dev/sr0 is write-protected, mounting read-only.

I usually get "sr0" errors when it's a bad burn. Almost always actually. If you verified the iso try to reburn the disk at a slower speed.

Yeah that's what I meant. Try to burn a new cd at a slower speed. When the new one is done create a hashsum of the new burn and compare it to the iso you used to burn it with. I only say this because a few times in the past when I had sr0 errors while booting live cds it was because the disk was messed up and I had to burn it again.
