Topic: error on new element uuid (AMD Ryzen)

the uuid element is always {ffffffff-ffff-4fff-bfff-ffffffffffff} if a new element is created

info: in QT on startup
WARNING: CPU random generator seem to be failing, disable hardware random number generation
WARNING: RDRND generated: 0xffffffff 0xffffffff 0xffffffff 0xffffffff

AMD shipped Ryzen 3000 with a serious microcode bug in its random number generator.

Can I adjust the uuid myself in the project?

You could try to upgrade your AMD microcode package. (amd64-microcode (3.20191218.1))
Or maybe upgrade to latest 5.4.6 vanilla kernel..

Re: error on new element uuid (AMD Ryzen)

Hi, this was my mistake the element library was made with QElectroTech V0.61, and converted with V0.8 with the failed CPU.
(suse provides QElectroTech Version 0.61 standard.)

You could try to upgrade your AMD microcode package

I tried is unsuccessful.

upgrade to latest 5.4.6 vanilla kernel

This will break my virtualbox.
(ps: updating the BIOS works)

Thank you for the support.

Hi,

you have AppImages if you want new versions, just wget and chmod +x.

Virtualbox Version 6.1.0 r135406 (Qt5.12.5) run on 5.4.6 kernel.
