All you need is to run guc firmware or vp8enc from multimedia/libva-utils. Both of them trigger it instantly. I workarounded it with updating linux_reservation.c to up to date version (really to 5.3) and moving critical section start in reservation_object_add_shared_fence() routine down to RCU_INIT_POINTER macro. There were lot of dma_fence changes in 5.0-5.4 timeframe, so it may have sense to start fixing the bug after drm-kmod reaches v5.4 -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-x11 To unsubscribe, send any mail to "[email protected]"
