I have recently had two display hangs on my Sandy Bridge system running drm-fbsd12.0-kmod-4.16.g20190430, libdrm-2.4.97,1, and mesa-dri-19.0.0_3. (Note the versions as some are not committed to ports at this time.) The first occurred when attempting to resume from suspend and the second was during normal use. Similar error in the log: [drm] GPU HANG: ecode 6:0:0x7ffbfff9, in Xorg [100468], reason: Hang on rcs0, action: reset drmn0: Resetting chip after gpu hang drmn0: Resetting chip after gpu hang drmn0: i915_reset_device timed out, cancelling all in-flight rendering. The following came after an attempt to unload i915kms and is probably not surprising. System panic followed. Warning: memory type drm_driver leaked memory on destroy (3 allocations, 64 bytes leaked). Warning: memory type drm_kms leaked memory on destroy (2 allocations, 1088 bytes leaked). -- Kevin Oberman, Part time kid herder and retired Network Engineer E-mail: rkoberman@gmail.com PGP Fingerprint: D03FB98AFA78E3B78C1694B318AB39EF1B055683
