---One line summary of the problem:
kernel panic in kernel 2.6.0-test5-bk11

---Full description of the problem/report:
This morning I tried the newest kernel version 2.6.0-test5-bk11.
It didn't boot. Instead there was a kernel panic which looked like
this:

<0> Kernel panic: Attempted to kill init!

I had a problem with the bk10 kernel too, which I already sent to the software raid mailing list (I use raid0 with lvm - see below). I guess this problem is related because it says something about md in the kernel panic. But because I am not shure about that I'm sending it to linux-kernel@xxxxxxxxxxxxxxxx
The panic occurs shortly after the linux kernel is loaded. It prints some stuff first and then panics. I guess the panic occurs when it tries to load init.

---Keywords (i.e., modules, networking, kernel): kernel, raid, lvm

---Kernel version:
2.6.0-test5-bk11 (this is not from /proc/version since I have to use the 2.6.0-test5-bk3 - which works fine - to write this mail)

---Software (add the output of the ver_linux script here)

root@chaos:/usr/src/linux/scripts # ./ver_linux
If some fields are empty or look unusual you may have an old version.
Compare to the current minimal requirements in Documentation/Changes.
