Thank you for taking the time to report this bug and helping to make Ubuntu better. We are sorry that we do not always have the capacity to look at all reported bugs in a timely manner. There have been many changes in Ubuntu since that time you reported the bug and your problem may have been fixed with some of the updates. It would help us a lot if you could test the current Ubuntu development version (10.10). If you can test it, and it is still an issue, we would appreciate if you could upload updated logs by running apport-collect bug #, and any other logs that are relevant for this particular issue. -- Turning wireless switch on causes system to slow down https://bugs.launchpad.net/bugs/325470 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

Any other ideas? I'm planning on upgrading to Jaunty on this weekend, nevertheless, there could be more people affected.

Booted computer with wireless switch on. But if I deactivate wireless and try to activate it again, it doesn't work, so nothing happens.

The new module name is iwlagn. You can try to use your wireless card by booting *with* switch on to see if that works.

[Bug 325470] Re: Turning wireless switch on causes system to slow down
@Id2ndR, Already downloaded Jaunty, but I can't report if this problem is happening on Jaunty, since wireless connections are disabled. The wireless card is recognized, but Ubuntu won't let me use wireless networks, even if the switch is on, and of course, no slowdown ocurrs, because it's like there wasn't a wireless network card; the Network Applet says wireless is disabled and lsmod says that there's not any 'iwl4965' module loaded. I've found other issues on Jaunty as well, where should I report them? -- Turning wireless switch on causes system to slow down https://bugs.launchpad.net/bugs/325470 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
[Bug 325470] Re: Turning wireless switch on causes system to slow down
Please, could you run top command while you're tuning on the switch and tell us if the is one process that use all the CPU ? Would you be willing to test the latest pre-release of Jaunty - http://cdimage.ubuntu.com/releases/jaunty/ . You should be able to test via a LiveCD. It would be helpful to know if this trouble exists in the upcoming Jaunty release. Please let us know your results. Thanks.

These are screenshost of the requested actions: - GNOME System Monitor before switching wireless on: http://www.fileden.com/files/2007/1/17/654676/gsm-before.png - 'top' command output before switching wireless on: http://www.fileden.com/files/2007/1/17/654676/top-before.png - GNOME System Monitor, while and after turning wireless on (the moment when wireless is turned on is marked with a green oval): http://www.fileden.com/files/2007/1/17/654676/gsm-switching.png . After some tests I did, there's always a peak after switching, sometimes it peaks to 50% or 60%, sometimes to full 100%, then goes back to normal. - 'top' command output when switching wireless on: http://www.fileden.com/files/2007/1/17/654676/top-switching.png I'm starting to download the latest pre-release of Jaunty.

About if there is any process using all the CPU, there's no really one, *sometimes* Xorg or another process called 'ksoftirqd' get high quotes, but don't get to the 100%. -- Turning wireless switch on causes system to slow down https://bugs.launchpad.net/bugs/325470 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
[Bug 325470] Re: Turning wireless switch on causes system to slow down
The screenshots aren't such usefull because we don't know what process use the CPU. The CPU usage is higher during about 2 seconds. You need to find witch process consume more CPU after te switch. Maybe it's the 'ksoftirqd' as you say. Xorg is related to the video, not to the wireless switch. -- Turning wireless switch on causes system to slow down https://bugs.launchpad.net/bugs/325470 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
[Bug 325470] Re: Turning wireless switch on causes system to slow down
@ld2ndR, I did some more tests running the 'top' command, this is what I've found out: When the switch is off, Xorg, Firefox, Amarok or other programs use variable percentages of CPU, below the 40%. When the switch is turned on, the slowdown ocurrs and 'top' doesn't show any noticeable change on the processes' CPU usage; iwl4965/0 appears and uses about 1% of CPU, then dissapears; and after a few seconds 'ksoftirqd/0' appears and gets to the top using always percentages above 90%. If I turn the switch off after that, sometimes everything goes back to how it was before turning the switch on, and sometimes 'ksoftirqd/0' stays at the top, without changes on its 90%+ CPU usage. I googled about this 'ksoftirqd' program, and if found that ksoftirqd is a per-cpu kernel thread that runs when the machine is under heavy soft-interrupt load. (http://www.tin.org/bin/man.cgi?section=9topic=ksoftirqd), I don't know what that means, though :P. Also I found something related to its heavy CPU usage at http://lkml.indiana.edu/hypermail/linux/kernel/0407.3/0382.html. I hope I've given some useful hints about this problem, otherwise please tell me what else can I do. -- Turning wireless switch on causes system to slow down https://bugs.launchpad.net/bugs/325470 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

[Bug 325470] Re: Turning wireless switch on causes system to slow down
** Description changed: My computer's wireless card activates by using a switch. When I turn the switch on to use wireless networks, the computer slows down *very* noticeably for a few seconds (two or three) and goes back to normal. The cursor freezes or moves very slowly, and if there is music playing, it stutters (which is annoying). That doesn't happen when I turn the switch off, it only happens when I turn the switch on. The card is an Intel PRO/Wireless 4965 AG or AGN Network Connection, using the iwl4965 driver. I'm having this problem long time ago, but I hadn't reported this any sooner because it didn't seem so annoying as it is now.
