Hi dmdmdm, Please be sure to confirm this issue exists with the latest development release of Ubuntu. ISO CD images are available from http://cdimage.ubuntu.com/releases/ . Please then run following command from a Terminal (Applications-Accessories-Terminal). It will automatically gather and attach updated debug information to this report. apport-collect -p linux-image-`uname -r` 178151 Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream- testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results. Thanks in advance. [This is an automated message.

[This is an automated message. Apologies if it has reached you inappropriately.] This bug was reported against the linux-meta package when it likely should have been reported against the linux package instead. We are automatically transitioning this to the linux kernel package so that the appropriate teams are notified and made aware of this issue. Thanks. ** Package changed: linux-meta (Ubuntu) = linux (Ubuntu) -- setting /sys/kernel/uids/uid/cpu_share to 1 causes the scheduler to give most of the cpu time to this uid https://bugs.launchpad.net/bugs/178151 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

maybe the bug is caused by the line se-load.inv_weight = div64_64((1ULL32), shares); in set_se_shares in sched.c? if shares is 1, div64_64 returns 132, but inv_weight is long(32 bit), and only the 33th bit is 1, so inv_weight is 0... -- setting /sys/kernel/uids/uid/cpu_share to 1 causes the scheduler to give most of the cpu time to this uid https://bugs.launchpad.net/bugs/178151 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
