Hi Christoph,
I test kernel from your 'dma-alloc-always-zero' branch, and as
I can see we have DMA peripherals (like USB) broken.
I would be really surprised if that is caused by the patch to add
the zeroing.
Me too :)
Can you check which commit caused the issue by bisecting
from a known good baseline?
Yep. At least kernel build from v4.20-rc4 (which is base for your branch)
seems to work fine.
