Hi Bill,
00000002 is a floating point divide-by-zero. So this is rather harmless,
although who knows what the lt-align program (pid 4828) thought of it.
I believe the userspace process gets terminated with SIGFPE.
The printout is coming from kernel function float_raise() which is defined
in arch/arm/nwfpe/fpmodule.c line 173, with flags defined in softfloat.h in
the same directory.
Cheers,
-Ralph
