[Bug 837076] Re: [iwlagn] Intel Centrino Ultimate-N 6300 AGN and packet loss
Thank you for taking the time to file a bug report on this issue. However, given the number of bugs that the Kernel Team receives during any development cycle it is impossible for us to review them all. Therefore, we occasionally resort to using automated bots to request further testing. This is such a request. We have noted that there is a newer version of the development kernel than the one you last tested when this issue was found. Please test again with the newer kernel and indicate in the bug if this issue still exists or not. If the bug still exists, change the bug status from Incomplete to Confirmed. If the bug no longer exists, change the bug status from Incomplete to Fix Released. Thank you for your help, we really do appreciate it. ** Changed in: linux (Ubuntu) Status: Confirmed = Incomplete ** Tags added: kernel-request-3.0.0-12.20 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/837076 Title: [iwlagn] Intel Centrino Ultimate-N 6300 AGN and packet loss To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/837076/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 837076] Re: [iwlagn] Intel Centrino Ultimate-N 6300 AGN and packet loss
Would it be possible for you to test the latest upstream kernel? It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . If possible, please test the latest kernel (Not a kernel in the daily directory). Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag(Only that one tag, please leave the others). 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. If this bug is fixed by the mainline kernel, please add the following tag 'kernel-fixed-upstream-KERNEL-VERSION'. For example, if kernel version 3.1-rc9 fixed and issue, the tag would be: 'kernel-fixed- upstream-v3.1-rc9'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Thanks in advance. ** Tags added: needs-upstream-testing ** Changed in: linux (Ubuntu) Status: Incomplete = Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/837076 Title: [iwlagn] Intel Centrino Ultimate-N 6300 AGN and packet loss To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/837076/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hi Brad, It still seems to be happening with 3.0.0-11.18.
