%SECTION0{name=LinuxKernelPanicsBecauseInitProessDies}% Linux Kernel Panics because "init" process dies

   Question:: I once had a running system but suddenly, without any changes,
     the Linux kernel started crashing because the "init" process was dying
     each time I tried to boot the system, for example like that:
     <verbatim>
...
VFS: Mounted root (nfs filesystem).
Freeing unused kernel memory: 140k init
init has generated signal 11 but has no handler for it
Kernel panic - not syncing: Attempted to kill init!
     </verbatim>
   Answer:: You probably run your system with the root file system mounted
     over NFS. Change into the root directory of your target file system,
     and remove the file ="etc/ld.so.cache"=. That should fix this problem:
     <verbatim>
# cd /opt/eldk/ppc_6xx/
# rm -f etc/ld.so.cache
     </verbatim>
   Explanation:: Normally, the file ="etc/ld.so.cache"= contains a compiled list
     of system libraries. This file is used by the dynamic linker/loader =ld.so=
     to cache library information. If it does not exist, rebuilt automatically.
     For some reason, a corrupted or partial file was written to your root
     file system.
     This corrupt file then confused the dynamic linker so that it crashed
     when trying to start the =init= process.

   Question:: I cannot boot into my freshly installed ELDK Root-NFS because
     =init= dies with an unhandled signal like this:
     <verbatim>
Freeing unused kernel memory: 124k init
PHY: e0103320:00 - Link is Up - 100/Full
init has generated signal 4 but has no handler for it
Kernel panic - not syncing: Attempted to kill init!
Rebooting in 1 seconds..
     </verbatim>

   Answer:: Your CPU does not have a floating point unit, your kernel has
     no math emulation (=CONFIG_MATH_EMULATION=) enabled but you still try
     to boot into a rootfilesystem intended for FPU systems.<br>
     This is to be expected for example if you try to use a =ppc_6xx=
     rootfilesystem on an 8xx system.
