Hello, I can confirm the issue with makedumpfile on amd64. However, the crc32c module issue does not appear on amd64 and the module is indeed present in the smaller initrd created for kdump (present in /var/lib/kdump/initrd.img-4.8.0-11-generic). I will investigate the makedumpfile issue with 4.8 kernels. ** Also affects: makedumpfile (Ubuntu Xenial) Importance: Undecided Status: New ** Also affects: makedumpfile (Ubuntu Yakkety) Importance: Undecided Assignee: Taco Screen team (taco-screen-team) Status: New ** Also affects: makedumpfile (Ubuntu Trusty) Importance: Undecided Status: New ** Changed in: makedumpfile (Ubuntu Yakkety) Status: New => Confirmed ** Changed in: makedumpfile (Ubuntu Yakkety) Importance: Undecided => High ** Changed in: makedumpfile (Ubuntu Xenial) Assignee: (unassigned) => Louis Bouchard (louis-bouchard) ** Changed in: makedumpfile (Ubuntu Trusty) Assignee: (unassigned) => Louis Bouchard (louis-bouchard) -- You received this bug notification because you are a member of नेपाली भाषा समायोजकहरुको समूह, which is subscribed to Xenial.
