-ETOOEARLYINTHEMORNING.  static_cpu_has looks correct.

werner, your kernel survives:

for i in `find -name \*.o`; do objdump -j .altinstructions -r "$i"
2>/dev/null |grep R_ |grep -v R_386_PC32\ ; done

Can you try the same command in your build directory?

In the mean time, I'll see if I can reproduce the crash in qemu by
playing with -cpu.
