I've been seeing a lot of the following messages since the 4.16 series kernel (and other software updates, of course). I wonder if anyone can say what is going on, or has experienced this.
It's not a constant; in fact, the current 4.16.3-1-default has been up for two days before it produced the below log. When it happens, it may happen once or several times in a row, and the display shows a delay in updating, when opening a new window for example, or simply paging text. It then straightens out and behaves normally.
Apr 29 22:51:56 sgt.decathlon.org kernel: radeon 0000:00:01.0: swiotlb buffer is full (sz: 2097152 bytes) Apr 29 22:51:56 sgt.decathlon.org kernel: radeon 0000:00:01.0: swiotlb: coherent allocation failed, size=2097152
Hrm, I hoped that this sort of bug was addressed by the recent fixes in 4.16.y / stable branch. At least, amdgpu drivers seem working better, but radeon hits, too. Could you check the kernel in OBS home:tiwai:stable-dma32 repo? This might help reducing such allocation failures. thanks, Takashi -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
