[Linux] Freezes on Asrock X370 Taichi + C6 enabled

I think I noticed the pattern that causes the freeze. After normal boot everything works fine. But if I ever use suspend and then resume the computer, that's when the freeze happens after a while. I suppose the motherboard firmware does something wrong in case of resume from sleep (may be memory training doesn't work, or something of the sort). I suppose I should open a bug with Asrock?

I doubt that's related here, since this happens both with disabled and enabled C6 and Cool'n'Quiet. And my PSU is certified to handle C6 fine.

Also, the freeze doesn't happen right away after resume, but randomly, at some point after that. So it's more likely, that the motherboard doesn't initialize something properly on resume from suspend, and it eventually glitches out.

Things that come to mind - try another PSU; run some memtest from a live Linux USB; some UEFI leftovers from a flash;

Does this happen with all left @ auto?

maybe some further testing to help us -help you

have you tested with the ram set at 2133 safe ?

if not please do so ,it may help us determine if the ram needs tweaking

ok its a start to try and work out the issue

i feel i can help with ram settings if required (am4 and xmp makes a pigs ear of setting them stable)
