Thus, I think disabling SMP seems to cause, one way = or another, other issues, that aren't related to the problem of requiring SMP disabled in the first place. With SMP enabled on the R500, I did some video playback and had no crashes.= I'm assuming that the display blanking crashes and video crashes are related and happen when SMP is disabled. I also found this bug report that sounds very similar, but about different hardware: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D284275 I opened https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D286018 for the kern.smp.disabled=3D1 crashes because I feel it is probably a separate issu= e. --=20 You are receiving this mail because: You are the assignee for the bug.=
