Thanks, so the kernel isn't oopsing, so that's a good sign. Can you run strace on fwts, e.g.
sudo strace fwts uefirtvariable
and capture the output. I am expecting to see it break on an ioctl() call to the fwts UEFI kernel test driver, in which case, it will clearly mean that that the UEFI run time service is the root cause.
