Two weekends ago I did a normal system update and got kernel 5.10. Since then, I've been getting a lot of this: Apr 01 22:24:41 hostname kernel: [drm:amdgpu_ttm_backend_bind [amdgpu]] *ERROR* failed to pin userptr Apr 01 22:24:41 hostname kernel: ------------[ cut here ]------------ Apr 01 22:24:41 hostname kernel: kernel BUG at mm/slub.c:304!

AFAICT, things were fine right before that. Is this a known thing? |

It's a problem with your kernel, not with BOINC or the applications thereunder. Search Google for "[drm:amdgpu_ttm_backend_bind [amdgpu]] *ERROR* failed to pin userptr" and you'll find a lot of patches for different kernel versions. E.g. This patch set is to fix a bug in amdgpu / radeon drm that results in a crash when dma_map_sg combines elemnets within a scatterlist table.https://lkml.org/lkml/2020/3/25/204 |
