[Bug 991232] Re: 14e4:432b Regression in wireless performance when on battery power
@Ryan, Can you provide some information on the status of the patch with regards to getting it merged upstream? Has it been sent upstream, what sort of feedback has it received, is it getting applied to a subsystem maintainer's tree, etc? People affected by this bug are probably wondering why the kernel team doesn't just apply the patch and fix it. The reason is that the kernel team is reluctant (not opposed) to apply any patch to a stable kernel that is not from upstream. Applying patches that don't come from upstream add greatly to the support of the kernel as other upstream patches may touch the same area as the non-upstream patch and may prevent them from applying cleanly. ** Changed in: linux (Ubuntu) Status: Confirmed => Triaged -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/991232 Title: 14e4:432b Regression in wireless performance when on battery power To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/991232/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 991232] Re: 14e4:432b Regression in wireless performance when on battery power
The bug was a regression in Maverick relative to Lucid, but it has been present in every release since Maverick, so at this point it's just a bug that has been around for at least 2 years. It may not be practical to fix the bug in the bcmwl drivers, but the workaround is only a two-line patch with minimal impact. I have attached the patch that implements the workaround only for wl drivers and retains the same behavior for all others. ** Patch added: "Patch to disable power-saving for wl driver" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/991232/+attachment/3212388/+files/wl-battery-performance-fix.patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/991232 Title: 14e4:432b Regression in wireless performance when on battery power To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/991232/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
Re: [Bug 991232] Re: 14e4:432b Regression in wireless performance when on battery power
@Joseph Salisbury: not sure this is a regression, the original bug report was https://bugs.launchpad.net/ubuntu/+source/linux/+bug/651008 which expired because it was reported on maverick for which support had expired. the problem still existed in 12.04, Christopher M. Penalver (penalvch) asked me to file a new report for 12.04, I copied the subject from that bug report.
