I see lots of kworker cpu usage on 3.9rc7 today but my mouse isn't slowing down. I can't run perf top to see why on that version due to the following:
# perf top perf_3.9.0-030900rc7 not found You may need to install linux-tools-3.9.0-030900rc7 Which does not appear to be available. -- top - 12:26:05 up 20:21, 3 users, load average: 0.92, 0.87, 0.86 Tasks: 247 total, 4 running, 242 sleeping, 0 stopped, 1 zombie %Cpu(s): 2.1 us, 7.3 sy, 0.0 ni, 88.4 id, 1.8 wa, 0.0 hi, 0.4 si, 0.0 st KiB Mem: 8066360 total, 5332144 used, 2734216 free, 246624 buffers KiB Swap: 8388604 total, 0 used, 8388604 free, 1293252 cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 10735 root 20 0 0 0 0 S 10.3 0.0 0:34.59 kworker/u:2 10802 root 20 0 0 0 0 R 7.0 0.0 0:11.06 kworker/u:3 648 root 20 0 0 0 0 R 4.3 0.0 3:15.49 kworker/1:2 10615 root 20 0 0 0 0 S 3.6 0.0 0:51.88 kworker/0:2 2708 ccheney 20 0 881m 211m 48m S 1.7 2.7 17:13.53 chromium-browse 689 root -51 0 0 0 0 S 1.0 0.0 3:36.76 irq/46-iwlwifi 2785 ccheney 20 0 1378m 426m 29m S 1.0 5.4 12:41.83 chromium-browse 7037 ccheney 20 0 606m 74m 28m R 1.0 0.9 8:04.97 chromium-browse 1151 root 20 0 291m 37m 26m S 0.7 0.5 4:11.79 Xorg 9946 ccheney 20 0 649m 21m 13m S 0.7 0.3 0:00.85 gnome-terminal 10951 root 20 0 20640 1608 1084 R 0.7 0.0 0:00.03 top 2488 ccheney 20 0 571m 19m 13m S 0.3 0.2 0:09.67 indicator-apple 2743 ccheney 20 0 933m 124m 15m S 0.3 1.6 3:04.22 chromium-browse 2854 ccheney 20 0 935m 74m 20m S 0.3 0.9 0:58.86 chromium-browse 3365 ccheney 20 0 977m 139m 21m S 0.3 1.8 1:31.61 chromium-browse 7483 ccheney 20 0 951m 77m 21m S 0.3 1.0 0:09.68 chromium-browse 10695 ccheney 20 0 949m 76m 20m S 0.3 1.0 0:05.38 chromium-browse -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/957298 Title: Mouse is very slow after starting a session on Precise Status in The Linux Kernel: Unknown Status in “linux” package in Ubuntu: Fix Released Status in “xserver-xorg-video-intel” package in Ubuntu: Invalid Bug description: I made a fresh install of Precise on a Lenovo X200 a couple weeks ago. When I start a new session after booting, the mouse is very slow and it feels like something might be taking up lots of resources on the system.
