Yes, Exactly.  As I understand it they moved more of the logic
from the Kernel to the userland tools (module-init-tools) code
which made features like versioning and stuff much easier.

  This is interesting cause of the changes made was to make it
so that it passed the fops20 tests, and The Linux Kernel Test
project, also, gives the chagnes passes on the floating point
stuff.



  I'm sorry, but I'm no good with ltrace/strace outputs.  I do
better with gdb's bt back traces.  If you feel like it can you
get an bt of the FPE?  Maybe Dan or someone else can make sense
of the trace and point use in the right direction.

What could have changed to cause floating point exceptions? I
checked

that my configuration files could not be causing the problem
by

temporarily moving them out of the way. Is this a Linux kernel
2.6

change or a coLinux change? Any thoughts or suggestions? What

information is needed to debug this?
