Bug#927094: additional reports

Dear maintainers,

Intel microcode
---------------

I updated my machine's BIOS, to confirm the TSC_DEADLINE issue.

* BIOS update made it clear.

* uninstalled intel-microcode; no error log again.

Obviously, it is about thee Intel's microcode issue.

About nouveau, nvidia-driver, and GeForce 1030
----------------------------------------------

* uninstall nvidia-driver (re-enable nouveau) made
   tty resolution back, 1920x0180.

* with and without nouveau, GDM, GNOME, and Firefox
   performance issue remains.

My conclusion
-------------

* Buster with GeForce 1030 as a primary video
   does not seems okay, if you want Buster "main" only.

* We should update BIOS for Intel microcode updates
   to make it okay without non-free intel-microcode package.

* Also I turned on ALPM since the Stretch clean install,
   I could not confirm any data loss, etc.

   This is very nice. I am considering all my box ALPM BIOS
   setups enabled, after Buster became stable.

Honestly, I did not plan to use the box by that configurations.

I have a GeForce 1030 card, which is very power efficient.
That's why.

I think this case is over, so I would close this ASAP.

Thanks for reading these reports.

Regards.
