Public bug reported:
With intel-microcode 3.20151106.1, my laptop is fine
With intel-microcode 3.20180425.1, Xorg crashes with SIGABRT in
__memcpy_avx_unaligned()
All other packages are at the most recent release. I have been back and
forth many times and I am quite sure that updating the microcode results
in frequent Xorg crashes.
