Disclosure :
1 : The CPU is a AMD FX-9590 ( Fam15h )
2 : Kernel command line parameter "eagerfpu=on" is being used.

This kernel option was causing constant kernel hard locks.
-----
General setup --> [ ] CPU isolation.
-----
Anything that accessed the FPU would cause the CPU's ( SMP ) to "loose
sync".

With the recent profile change, a lot of 32bit software had to be
re-compiled.

GCC locked up constantly while compiling "libssp".
The packages 'gmp,mpfr,mpc,isl,ffii' also caused lock-ups.
The audio/video codecs had lock-ups during the re-compile if any
assembler was used.
FFMPEG also locked up if 'hardcoded tables' was used, as well.

If you have a working FPU/Math Co-Processor, be very wary of this option.
