Hi John, > >I know RX570 (polaris) should stay at PCI3 as far as I know. > > Yep... thought I remembered you mentioning having a 5700XT though... is that in a different system ? I am using a RX570, the guy from reddit changed from R600 to an 5700XT and it seems it did solve his reboot problems. As the system is rock solid with windows-10 and others seem to experience similar behaviour I've decided to file a bug at the kernel's bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=206903 Thanks for your suggestions & best regards, Clemens > > ________________________________ > From: Clemens Eisserer <linuxhippy@xxxxxxxxx> > Sent: March 9, 2020 2:30 AM > To: Bridgman, John <John.Bridgman@xxxxxxx>; amd-gfx@xxxxxxxxxxxxxxxxxxxxx <amd-gfx@xxxxxxxxxxxxxxxxxxxxx> > Subject: Re: Possibility of RX570 responsible for spontaneous reboots (MCE) with Ryzen 3700x? > > Hi John, > > Thanks a lot for taking the time to look at this, even if it doesn't > seem to be GPU related at first. > > > OK, that's a bit strange...
