If you have an old linux kernel, gdb will not work due to bugs in the linux
kernel ptrace support.  I submitted two patches to fix two problems in Fall
2018.  Then there was a third patch to add support for FP registers but you
only need that one if you want to look at FP registers.  You definitely
need the first two patches in the kernel.
