This is no longer an issue for me.

[Bug 745220] Re: Kerneloops in mac20811 on Macbook Air
Peter Hedlund, thank you for reporting this and helping make Ubuntu better. This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ . If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report. apport-collect -p linux Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream- testing' tag. 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. Please let us know your results. Thanks in advance. ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/745220 Title: Kerneloops in mac20811 on Macbook Air To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/745220/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 745220] Re: Kerneloops in mac20811 on Macbook Air
I think most of us would like in-kernel drivers to work perfectly and not have to rely non-free kernel modules. However until that happens, occasionally the non-free kernel modules will provide greater reliability. I too hope this changes soon. P.S. Good news - Looking at the kernel 2.6.39 changelogs it seems broadcom developers are working madly to improve brcm80211 right now. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/745220 Title: Kerneloops in mac20811 on Macbook Air -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 745220] Re: Kerneloops in mac20811 on Macbook Air
Thanks for your response. But that is a little like saying I might find running Mac OS X even more stable... Being able to use the new in-kernel driver was one major reason for upgrading to Natty. It is fairly stable and the fact that it reconnects almost instantly when resuming from sleep is a major step forward. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/745220 Title: Kerneloops in mac20811 on Macbook Air -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 745220] Re: Kerneloops in mac20811 on Macbook Air
You might find the Broadcom STA driver much more stable than brcm80211 which is still in staging in kernel 2.6.38... You can switch to the stable STA driver by: 1. In Additional Drivers, install "Broadcom STA wireless driver". This installs the "wl" kernel module (bcmwl-kernel-source). 2. Work around bug #747002: sudo echo "blacklist brcm80211" > /etc/modprobe.d/blacklist-bcrm80211.conf This works well on a MacBook Air 3,1. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/745220 Title: Kerneloops in mac20811 on Macbook Air -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
