I started using Blender at v2.80 and it is constantly crashes ever since, after approximately 2-3 mins after startup. I use Arch Linux with nouveau driver. Blender crashes either with Eevee and Cycles engine chosen. Every time at some point Blender freezes my whole desktop env. (with mouse cursor) and then successfully crashes, OR (approximately with 1:1 chance) do not unfreezes desktop and gets me hard rebooting machine.

Last time I called blender with --log <file> and --debug options and saved project file, but there was no files except project file in the working directory. The last lines Blender returned to my terminal that I could see after the crash scrolling all the way up were:

  • a lot of nouveau: 0x<8-digit hex number>
  • blender: ../libdrm-2.4.101/nouveau/pushbuf.c:723: nouveau_pushbuf_data: Assertion `kref' failed.
  • Aborted (core dumped)

I see bug is highly likely related with nouveau.

Nouveau drivers aren't officially supported, the minimum requirements state that the official Nvidia drivers have to be installed when using one of their graphics cards.

NVIDIA: GeForce 400 and newer, Quadro Tesla GPU architecture and newer, including RTX-based cards, with NVIDIA drivers (list of all GeForce and Quadro GPUs)
