It occurs to me, quite belatedly, that it may be worth asking the author, reviewers, and signers of the change in question their thoughts on this bug report: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=990279 In particular, on ppc64 systems, Linux typically is configured to use a 64KiB page (i.e., shift 16) rather than 4KiB (shift 12) page. It looks, however, that AMDGPU_GPU_PAGE_SIZE is always 4096, and so something (perhaps in userspace, even, eek?) is requesting 4KiB-but-not-64KiB alignment of this buffer. Any insight you could offer would be deeply appreciated. Thanks, --nwf;
