[Bug 250139] Re: iwl4965: Can not allocate SKB buffers
Moving status from Fix Committed to Fix Released based on the fact that linux-backports-modules-2.6.27 should resolve this issue for Intrepid and Joel commented he's moved to the 2.6.28 Jaunty kernel which also should not exhibit this issue.

Hi Matt, Bug 276990 sounds like it might be the kernel panic you are seeing. The bug reporter there commented "the Oct-1-2008 compat-wireless iwlagn module fixes the kernel panic issue". It sounds like Tim is working on doing a backport right now to provide and updated wireless stack so hopefully this will at least resolve the panic.

Yes, I have rebooted since installing the updates. I believe the only time I saw the SKB errors was when my machine was running out of memory and oomkiller was invoked. In the mean time I have switched from Ubuntu's kernels to running 2.6.28 release candidates, so it is unlikely I will see this again with an Intrepid kernel again.

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.

This still happens in 2.6.27-2.3, reproduced in the same fashion.

[Bug 250139] Re: iwl4965: Can not allocate SKB buffers
The SKB allocation failures can be triggered fairly reliably in 2.6.27-2.3 by causing some network traffic (using e.g. iperf) and writing data to my USB harddrive (using dd). Running just iperf or dd is fine. However, as soon as I run both at the same time, I get a lot of "iwlagn: Can not allocate SKB buffers" messages. Note that I didn't even touch the kill switch (which doesn't work anyway). Also, I haven't found any page allocation failures in my logs. ** Attachment added: "dmesg.txt" http://launchpadlibrarian.net/17411164/dmesg.txt -- iwl4965: Can not allocate SKB buffers https://bugs.launchpad.net/bugs/250139 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

Joel, just to confirm, have you rebooted since installing the l-b-m package? Installing the package alone won't cause the l-b-m version of the driver to be used if the mainline driver is already loaded. -- iwl4965: Can not allocate SKB buffers https://bugs.launchpad.net/bugs/250139 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 250139] Re: iwl4965: Can not allocate SKB buffers
Yes, I have rebooted since installing the updates. I believe the only time I saw the SKB errors was when my machine was running out of memory and oomkiller was invoked. In the mean time I have switched from Ubuntu's kernels to running 2.6.28 release candidates, so it is unlikely I will see this again with an Intrepid kernel again.

It looks like linux-backports-modules has pulled in an updated wireless stack from upstream: linux-backports-modules-2.6.27 (2.6.27-7.3) intrepid; urgency=low [Tim Gardner] * Added iwlwifi firmware * Added the upstream compat-wireless-2.6 tree. * Updated compat-wireless to wireless-testing tag master-2008-10-14 * Set CONFIG_WIRELESS_OLD_REGULATORY=y by default. It might be good to test with linux-backports-modules and confirm if this bug is still an issue. It will at least provide us and Intel with some additional feedback.
