https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D235487 --- Comment #11 from Jan Beich <jbeich@FreeBSD.org> --- Created attachment 202111 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D202111&action= =3Dedit possible workaround Philip, can you try the attached patch? Found from https://github.com/DragonFlyBSD/DeltaPorts/commit/630507ebacd5 If it doesn't help bisecting upstream commits (time-consuming due to patch churn) maybe required as I don't have hardware old enough to be compatible = with drm-legacy-kmod. (In reply to Martin Birgmeier from comment #10) > Is this related although using the NVidia driver in this case? nvidia-driver has its own DDX/DRI/libGL implementation, so the stability on= ly depends on xorg-server and kernel changes. mesa-dri is only used for <GL/internal/dri_interface.h>. As GLVND isn't in ports yet libGL implementa= tion cannot be switched at runtime. > I have another machine with similar crashes since about the same > time, this time using Intel 82945GM (945GM GMCH). Maybe related if using iGPU. 945GM is Calistoga, even older than Ironlake. https://en.wikipedia.org/wiki/List_of_Intel_graphics_processing_units > A third machine using an ATI Radeon HD 4290 does not seem to be affected. Only Intel iGPU on drm-legacy-kmod or in-base drm2 appear to be affected. > The second machine does not even run any 3D clients, just a simple X > server with oclock running on top of it (no graphical login > manager). mesa-dri is used for DRI2 and AIGLX. However, according to bug 235203 it on= ly affects modesetting(4x). --=20 You are receiving this mail because: You are the assignee for the bug.=
