It most definitely isn't a final solution. However, the i386 PTI changes
are what's causing you problems and it is a temporary workaround to
disable it in the meantime until we can identify the proper fix. Once
the bug is fixed and you install the updated kernel with the bug fix,
you should remember to remove the 'nopti' boot option.
