Hi Carlos,

I  believe you ran into:

https://sourceware.org/bugzilla/show_bug.cgi?id=3D28033
https://www.intel.com/content/www/us/en/support/articles/000059422/processo=
rs.html

Specifically your CPU is listed as

06_9EH <=3D0xC 8th/9th Generation Intel=C2=AE Core=E2=84=A2 Processors and =
Intel=C2=AE
Pentium=C2=AE Processors based on Coffee Lake microarchitecture

I think we should black list all CPUs on the list.
