I tried out a recent NetBSD 10.0 BETA snapshot after a long time. The issue of loss of acceleration on rotation is still open. http://gnats.netbsd.org/cgi-bin/query-pr-single.pl?number=57143
This issue is identified in the pre-release checklist https://wiki.netbsd.org/releng/netbsd-10/ It is described as "Many of these are waiting for feedback." However 57143 is not waiting for feedback. It is "Open". Is there any chance of it making it to 10? -- Mayuresh
