The issue is related to a bug in the x86/kexec component of the Linux kernel, where the call to `cc platform has()` triggers a fault and system crash if call depth tracking is active. This occurs because the GS segment has been reset by `load segments()` and `GS BASE` is now 0, but call depth tracking uses per-CPU variables to operate. The fix involves calling `cc platform has()` earlier in the function when GS is still valid.
