System hangs on both program and WebGL test page. Bisected to: eb1497e968bd4a0edc1606e8a6f708fab3248828 is the first bad commit commit eb1497e968bd4a0edc1606e8a6f708fab3248828 Author: Kenneth Graunke <<a href="mailto:kenneth@whitecape.org">kenneth@whitecape.org</a>> Date: Fri Jul 21 12:29:30 2017 -0700 i965/bufmgr: Allocate BO pages outside of the kernel's locking. Suggested by Chris Wilson. v2: Set the write domain to 0 (suggested by Chris). Reviewed-by: Matt Turner <<a href="mailto:mattst88@gmail.com">mattst88@gmail.com</a>> Reverting this commit (git revert eb1497e968bd) from the latest mesa master 18.1.0-devel (57b0ccd178bc) solved this hang. Looks like there is a problem in kernel driver handling that ioctl. Last working kernel in Ubuntu 16.04 LTS was 4.13.0-26-generic, hangs with 4.13.0-31-generic.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
