Working fine on my 2014 machine with MSI Z87-G43 (MS-7816) mobo, Intel(R) Core(TM) i7-4770K CPU, and AMD Radeon(TM) HD 8800 Series video card (x86_64).

Mga8-64 OK here

Was running backport kernel 5.12.13;
downgraded cpupower and kernel-userspace-headers,

dkms status tells me VirtualBox and nvidia-current are OK.
BOINC detects CUDA and OpenCL

Been using it now and then today
Plasma desktop, using Thunderbird, LibreOffice, Ktorrent, Nextcloud client, flatpak Firefox...
Video with sound in Mageia Firefox ESR
Stress test: While working with other things BOINC use all cores to 100%, videos do not stutter in Chrome, nor Firefox ESR but do in flatpak version.

VirtualBox running MSW7 64 bit OK: graphics, window resize, bidirectional clipboard, drag file from Dolphin to Explorer, folder sharing write protected and not, folder sharing, USB2 with plugin from upstream using USB stick, internet video playing in Firefox and Chrome.

type: security
subject: Updated kernel packages fix security vulnerabilities
CVE:
 - CVE-2020-26541
 - CVE-2021-22543
 - CVE-2021-35039
src:
  8:
   core:
     - kernel-5.10.48-1.mga8
     - kmod-virtualbox-6.1.22-1.10.mga8

description: |
  This kernel update is based on upstream 5.10.48 and fixes atleast the
  following security issues:

  The Linux kernel through 5.8.13 does not properly enforce the Secure Boot
  Forbidden Signature Database (aka dbx) protection mechanism. This affects
  certs/blacklist.c and certs/system_keyring.c (CVE-2020-26541).

  An issue was discovered in Linux: KVM through Improper handling of VM_IO|
  VM_PFNMAP vmas in KVM can bypass RO checks and can lead to pages being
  freed while still accessible by the VMM and guest. This allows users with
  the ability to start and control a VM to read/write random pages of memory
  and can result in local privilege escalation (CVE-2021-22543).

  kernel/module.c in the Linux kernel before 5.12.14 mishandles Signature
  Verification. Without CONFIG_MODULE_SIG, verification that a kernel module
  is signed, for loading via init_module, does not occur for a
  module.sig_enforce=1 command-line argument (CVE-2021-35039).

  Other fixes in this update:
  - ahci: Add support for Dell S140 and later controllers
  - ALSA: hda/realtek: fix mute/micmute LEDs for HP EliteBook 830 G8
  - ALSA: hda/realtek: fix mute/micmute LEDs for HP ProBook 445/450/630 G8
  - drm/amdgpu: fix bad address translation for sienna_cichlid
  - drm/sched: Avoid data corruptions
  - net: ip: avoid OOM kills with large UDP sends over loopback
  - iwlwifi: Add support for ax201 in Samsung Galaxy Book Flex2 Alpha
  - virtio_net: Remove BUG() to avoid machine dead
