Since no member of the Ubuntu kernel team has had a look at this, all I can do is speculate. I think this is the deal: the patch is not just a few lines of obvious bug-fixes, it is a rewrite of the way the bay and dock is handled. It removes the old bay-module completely for starters. Because of this and since there are a limited number of people that are bit by this bug, I think the chances that this patch will go in the stock 2.6.27 kernel are pretty slim. It is however included in the coming 2.6.28 kernel, but I have no idea if that will ever make it to Intrepid.
Anyway, I have prepared a new kernel based on 2.6.27-9.19 with the patches applied. I also finally got around to building a meta package which automatically installs the latest version of the patched kernel. Please see the updated installation instructions in the bug description. My ambitions are to follow the stable kernel releases (sorry Tobias, I just don't have the time to track the "proposed" kernel) and apply the patches as soon as possible after a new release. Since I have tried to follow Ubuntus guidelines for ppa-packages, the patched kernel will always be stable kernel version + 1, but will be "overridden" when a new official kernel version (with an ABI-bump) is released. Sorry for the inconvenience this may cause, but I have not come up with a better way. I guess you could uninstall the official linux-generic meta-package if you do not want any official kernels without the patch automatically installed, but it is not something I would recommend. And I will be sure to pass along your encouraging words to certain family members who are not always thrilled to see me hunched over my laptop at night :-) ** Description changed: After resuming from suspend to ram or suspend to disk, kacpid and kacpi_notify battles to keep CPU at about 90% if you have an extra battery in the media bay, or if you insert or remove an extra battery with the OS running. This is on a Dell Latitude D810 on all Ubuntu 2.6.27-x kernels so far. The bug seems to be present with Dell laptops only. Since there is a patch available upstream, I have posted a patched kernel to my PPA which resolves the problem for some of us. deb http://ppa.launchpad.net/gabriel-thornblad/ubuntu intrepid main deb-src http://ppa.launchpad.net/gabriel-thornblad/ubuntu intrepid main Install with: - sudo apt-get install linux-image-2.6.27-8-generic linux-headers-2.6.27-8-generic + sudo apt-get install linux-generic-dock -- [Intrepid] kacpid and kacpi_notify consumes all CPU after resume https://bugs.launchpad.net/bugs/280088 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
