This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- yakkety' to 'verification-done-yakkety'. If the problem still exists, change the tag 'verification-needed-yakkety' to 'verification-failed- yakkety'. If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

The kernel I'm working on in unstable (git://git.launchpad.net/~ubuntu- kernel/ubuntu/+source/linux/+git/unstable) will eventually become the Yakkety kernel. I've set NR_CPUS to 8K which is the default if you go above 512. I've already had a request to support a platform with over 1K cores. I'll leave it there unless we find through testing that it causes extraordinary RAM consumption or has some other deleterious side effect. ** Changed in: linux (Ubuntu Yakkety) Assignee: (unassigned) => Tim Gardner (timg-tpi) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1579205 Title: CONFIG_NR_CPUS=256 is too low To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1579205/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
