I appears the newer kernel resolves the issue. I downloaded the LiveCD Alpha5 Intrepid Ibex (x86_64) and could not reproduce the issue. -- network traffic pulsing https://bugs.launchpad.net/bugs/194832 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 194832] Re: network traffic pulsing
The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test: 1) If you are comfortable installing packages on your own, the linux- image-2.6.27-* package is currently available for you to install and test. --or-- 2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD. Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback. ** Tags added: cft-2.6.27 -- network traffic pulsing https://bugs.launchpad.net/bugs/194832 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 194832] Re: network traffic pulsing
Hi Guys, It unfortunately looks like this bug did not get resolved for Hardy. I'd like to move this bug forward for the upcoming Intrepid cycle. Beginning with the Intrepid Ibex 8.10 development cycle the linux- ubuntu-modules package was merged with the linux kernel source package. Therefore any future bugs that would have been reported against linux- ubuntu-modules should now be reported against just linux. I've gone ahead and opened this report against the linux kernel source package. It would be great if someone can confirm this bug does indeed still exist with the latest Intrepid Alpha release - http://www.ubuntu.com/testing . Thanks. ** Also affects: linux (Ubuntu) Importance: Undecided Status: New ** Changed in: linux (Ubuntu) Status: New = Incomplete -- network traffic pulsing https://bugs.launchpad.net/bugs/194832 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 194832] Re: network traffic pulsing
I experiance the same problem as descibed above on an AMD 3200 MB asus K8VSE with 1GB ram. 7.10 I have tested this with the onboard(88E8001 Gigabit Ethernet Controller) and an added (3c905B 100BaseTX [Cyclone]). Both give the same problem. As soon as an other ubuntu machine ( one of three others 2*7.4 +1*7.10 ) starts up in the network I have the problem resulting in a high load. The other machines are old PIII/ PIV (7.4) and dual core laptop(7.10) having less problems with this. An existing XP machine do not show any sign of this. Load on amd 3200 with no other machine in the network load average: 0.22, 0.19, 0.43 Load on amd 3200 with one machine (PIII) started up in the network load average: 0.93, 0.64, 0.50 The load can be 2 resulting in interupting all the work on AMD. After unplugging the PIII from the network the load drops direct. ** Attachment added: grafieken.jpg http://launchpadlibrarian.net/13579871/grafieken.jpg -- network traffic pulsing https://bugs.launchpad.net/bugs/194832 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

I can confirm this behavior in both gutsy i386 and AMD64 as well as hardy alpha5 i386.

okay, compiling the new e1000 driver seemed to do the job, i now get 40mbs, no pulsing, and would get more speed i guess if my other nic card wasn't limited to a mtu of 7000.

[Bug 194832] Re: network traffic pulsing
UPDATE: The previous post did work, and has set my mtu. however i am still experiencing the pulsing and slow speeds. The screen shot shows what i am talking about: The high speed activity it over HTTP and the lower speed is over samba (SMB) as you can see both signals are pulsing. Although setting the correct MTU has speed things up it still hasn't solved the pulsing problem. compiling the latest driver doesn't seem to do anything. ignore my post about the updated e1000 driver. ** Attachment added: clearly shows the slow speeds over SMB and pulsing. http://launchpadlibrarian.net/12172643/Screenshot-System%20Monitor.png -- network traffic pulsing https://bugs.launchpad.net/bugs/194832 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
