Dear Maintainer,

Two years ago I purchased a Qotom Q190N MiniPC and successfully installed
Debian 8.2, subsequently upgraded to 10.1. A second Qotom of the same model
purchased a few months ago fails to install, even with the latest inatallation
CD. Both hang after reporting "Installed discover (amd64)".

Further investigation revealed:

1. PCLinuxOS live disk and install also hang at what appears to be the same
point: hardware discovery.
2. Puppy Linux runs fine.
3. System Rescue CD 5.3.0 (Gentoo based) runs fine, as does the latest SRCD 7.0
(Arch based).
4. ArchBang Linux installs cleanly and runs fine.

From this I conclude that the hardware is OK, but the Debian and PCLinuxOS
hardware discovery utilities have not yet advanced to the hardware I am using.

I believe that Debian 10.1 uses the following utilities to identify hardware:

discover (2.1.2-5.2)
discover-data (2.2010.10.18)

However, even the latest install ISO fails using updated packages:

discover_2.1.2-8_amd64.deb
discover-data_2.2013.01.11_all.deb

Hardware listing of both Qotoms reveals them to be identical apart from a minor
change in CPU stepping. The SoC is an Intel Atom Bay Trail with four Celeron
J1900 cores, and during the interim between my purchases it moved from Stepping
8 to Stepping 9. However, this resulted in a change in CPU flags which may be
the problem:

Qotom #1 unique flags: cpuid pti tsc_known_freq tsc_reliable
Qotom #2 unique flags: ibpb ibrs ida kaiser md_clear stibp
