*** This bug is a duplicate of bug 1637520 *** https://bugs.launchpad.net/bugs/1637520 Is it really a good idea to mark this well-described bug as a duplicate of something that just describes a solution? I find one of the most valuable things we can do to propel the community forward is to have accurately described bugs so people can get together and discuss the same issue (even after a fix becomes available).

Tested with 4.9rc3 and things are working again (sweet and thanks!). I went back to 4.8.0.11 and it was still an issue there. As well as checking 4.4.0.34 and zero issues with that.

This could be related to IO scheduling. In the past Unity7 has been guilty of doing IO during graphics operations. So graphics performance was impacted by heavy IO. I haven't noticed this regression with kernel 4.8 myself. Perhaps because I've been using reasonably efficient SSDs? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1638278 Title: 4.8 kernel, under heavy load desktop unusable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1638278/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1638278] Re: 4.8 kernel, under heavy load desktop unusable
Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem? Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.9 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.

This happens for me as well. More then enough Mem/swap left. Easy to reproduce when compiling -j4. Testing with 4.4 and no issues.
