Description of problem: 
With an initrd created by recent versions of mkinitrd, boot from a 
"mkbootdisk --iso"-created boot CD fails on my system.  Relevant bit 
of boot messages (verbose version using nash-test for more info): 
 
Switching to new root 
exec of init (/sbin/init) failed!!!: 14 
Kernel panic: Attempted to kill init! 
 
Now unless I'm looking in the wrong header file, 14 is EFAULT, which 
from the execve man page means "filename points outside your 
accessible address space".  I wish that made sense to me... 
 
Version-Release number of selected component (if applicable): 
 
I've had this problem from current mkinitrd (4.0.5) back at least as 
far as 4.0.3.  4.0.0 worked fine (at least in this regard).  Not sure 
about 4.0.1 or 4.0.2; if you can point me to a place I can get those 
old versions, I'd be happy to retest with them. 
 
How reproducible: 
 
Using an affected version of mkinitrd, on my system, always.  
Unfortunately I have no idea which aspects of my system's 
configuration are causing the behavior.  I always boot off CD, having 
no boot partition configured, so I don't know if the CD booting is 
actually a factor. 
 
Additional info: 
 
Here's what things look like once I'm successfully booted:
