[Bug 746084] Re: Stuttering mouse with Natty Narwhal
** Description changed: Binary package hint: xserver-xorg-video-intel I just upgraded from Kubuntu 9.10 via 10.04 and 10.10 to 11.04-dev. Since 10.10 the mouse sometimes "stutters" while moving, freezing for a few hundred milliseconds. Similar behaviour has been reported for Maverick before (#595764, #599068, #662946, #658747), however in these cases it seems to have been limited to i8xx GPUs while I use an i945... Additionally, I could not find reports of this problem re-occuring (or still occuring) in Natty, so I'm reporting it here. The mouse stuttering / short freezes are much better than with Maverick, where even the sound was affected, but it's still pretty noticeable and annoying / distracting. Using "top", I noticed a kernel thread called "kworker" being listed among the top-5 processes in the process list refresh following such a "mouse stuttering". I'm not sure if any further information is neede, I'm happy to provide whatever I can to help resolve this problem.

Can someone who is feeling adventurous please test out any .39 kernel after rc2, there has been an update which indirectly affects kworker which I think is the root cause of this issue.

I have to same problem. Stuttering Mouse and Keyboard corresponding with CPU consuming kworker - processes. I noticed this since yesterday, before everything was fine.

Tried with a HP Mini 210-1020BR. Same issue when I enable USB Suspension.

Try disabling and post here what happens. Might work as a workaround 'till the devs work on it For now, I'm just unplugging my devices when not in use.

Mh, I've not yet tried to disable USB power save, but apparently we've got to do with two issues here, right? The kswapd-bug which seems to be solved and another bug with USB power saving which may or may not have been present before, but if it was, was suppressed by the more severe swapd problem and which surfaces now... Maybe someone with sufficient permission could split this bug, or should I simply open a new one if I observe the same USB power save behaviour, so that this bug can be closed? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/746084 Title: Stuttering mouse with Natty Narwhal -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 746084] Re: Stuttering mouse with Natty Narwhal
Seems like this bug only happens when the USB Suspension is enabled. At the moment I'm writing this, I'm on a netbook with a Celeron ULV 723 1.2GHz (no speedstep) and i915 drivers. Enabling USB Suspensions makes Kworker go mad and start eating all CPU Resources. It also kills the USB ports for every device (HID or not) Disabling USB Suspension is a workaround, but makes the energy consumption sligtly higher, depending on what's connected thru USB. On my case (I've only got a Microsoft nanoreceptor connected thru USB), it jumps from 6.5W to 8W Idle. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/746084 Title: Stuttering mouse with Natty Narwhal -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Rolling back to a 2.6.35 kernel solves the issue for me.
