Hello. First I will write my specs:
CPU: AMD Ryzen 5 2600 overclocked to 4,1 GHz
RAM: 16GB 3000MHz CL16
GPU: Gainward Phoenix RTX 2060 GS
MOBO: MSI B450-A PRO
SSD: Samsung 970 EVO Plus 500GB
Sound Card: Asus Xonar DGX
Dual boot Windows 10 and Manjaro KDE
When I am turning volume up and down very quickly, my computer is restarting. Then, after choosing Manjaro in GRUB menu, i can see for a few seconds this output:
[ 0.297044] mce: [Hardware Error]: CPU 5: Machine Check: 0 Bank 0: be80280000
[ 0.297044] mce: [Hardware Error]: TSC 0 ADDR fffdfc00d080 MISC d012000000000
000 IPID b000000000
[ 0.297044] mce: [Hardware Error]: PROCESSOR 2:800f82 TIME 1601135477 SOCKET
0 APIC c microcode 800820d
Then, system normally starts up.
Also sometimes, when I am starting YouTube video, system can also restart and show the same output like above.
On top of that, sometimes when I shutdown my computer, it is shutting down for 1 minute (when it normally takes 5 seconds), and after that 1 minute same output is shown.
I think it might have some relation with my dedicated soundcard. There are no native drivers for Linux for my soundcard, so I am forced to use these ones installed by default. If this can matter, I am plugging my headphones and microphone to front panel (i connected HD Audio header to my Xonar DGX).
