Description Thomas Backlund 2019-07-09 21:29:49 CEST 
Advisory:
Updated systemd packages fixes booting on new AMD Ryzen systems

On some AMD CPUs RDRAND will sometimes report success via the carry flag
but nonetheless return the same fixed value -1 in all cases. This appears
to be a bad bug in the CPU or firmware. This causes systems to fail to boot
after suspend/resume.

With the new Amd Ryzen 3xxx series that got released on July 7th, 2019 its
worse, as the system will fail to boot every time because no systemd service
will start properly.

This update adds a workaround to systemd so it ignores the invalid RDRAND
responses, thus allowing the system to boot.

In this update there is also a fix for udevd having a reversed conditional on
global property set, report causing some ENV variables being reported as not
set even if they are.

Note to testers, The Ryzen non-booting bug requires a AMD Ryzen 3xxx cpu to verify.

I have done so today with a brand new Ryzen 5 3600 that arrived here today.

So just install this update, and test that nothing breaks.

The udevd bug will hopefully be verified in bug 25027

Regardless, its the correct fix to do and comes from upstream

Note that this update already is in Cauldron since Mon 08 Jul 2019 11:55:48 PM CEST, so it's tested there too

Thomas, thanks so much for reporting the bug and the testing and followup.  I posted my advisory on Jul 8th on the forum: 

https://forums.mageia.org/en/viewtopic.php?f=8&t=12894

It is great it is already in Cauldron.  I assume your testing showed it not possible to boot/install/run Mageia 7.0.  Will Mageia have to release new 7.0 ISO images?  If not, how will Ryzen 3000 users work-around the bug to install 7.0?

PS- what motherboard did you use?  Is it X570 based?

On mga7-64

packages installed cleanly:
- lib64systemd0-241-8.1.mga7.x86_64
- lib64udev1-241-8.1.mga7.x86_64
- nss-myhostname-241-8.1.mga7.x86_64
- systemd-241-8.1.mga7.x86_64
- systemd-units-241-8.1.mga7.x86_64

no regressions observed
looks OK for mga7-64 on this system:

Dell product: Precision Tower 3620
Mobo: Dell model: 09WH54 
Card: Intel HD Graphics 530
CPU: Quad core Intel Core i7-6700 (-HT-MCP-)
PC-BIOS (legacy) boot
GPT partitions

(I've also been running systemd-241-9 on my cauldron install on this machine  for two days)
