  I disagree. The h-online.com articles, while not in bulletpoint style, are usually more detailed and better written, and currently the best way to dig into a new release.

Here's the commit: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=02f8c6aee8df3cdc935e9bdd4f2d020306035dbe http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6... the tree: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=tree;h=02f8c6aee8df3cdc935e9bdd4f2d020306035dbe;hb=02f8c6aee8df3cdc935e9bdd4f2d020306035dbe http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6... the diff: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=02f8c6aee8df3cdc935e9bdd4f2d020306035dbe;hp=1f922d07704c501388a306c78536bca7432b3934 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6... and the snapshot: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=snapshot;h=02f8c6aee8df3cdc935e9bdd4f2d020306035dbe;sf=tgz http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6... It'll probably be a bit/longer for it to be 'officially' listed on kernel.org as stable.

I wonder if they have the fixed the battery drain bug in this release. When I installed Ubuntu 11.04 on my netbook, it had that bug. Read it on reddit that it has something to do with regression or something. So I had to downgrade to 10.10 to go back to previous version of the kernel.
- JoshTriplett 15y ago
  Not exactly a regression. Current Linux started working around a BIOS bug that causes many people's systems to hang: namely, those BIOSes configure PCI Express devices to do Active State Power Management (ASPM), but tell the OS not to support ASPM, causing the system to go pear-shaped when the devices try to go into a low-power state. Linux now turns off ASPM on devices if the BIOS says not to use ASPM; that makes many people's systems more stable, at the cost of a bit more power usage. So, complain to your BIOS vendor, or turn off that workaround in Linux and take the risk that your system will become less stable.

    Im sure complaining to the BIOS vendor will work cough cough cough

    How does Windows work around this?

      We don't know right now. Someone is cheating.

      "Windows" doesn't, the device vendors do. I don't know anything about this particular bug, but it's no big deal: no doubt fixable for any given device with a quick patch ("If the DMI string is this and the BIOS says this, then it's lying and pretend it said this"). In the PC world, all the vendors have huge teams of engineers doing exactly this: applying hacks to get Windows running correctly on each new device. Then they package those hacks in per-device "driver" packages. This is the reason why, for example, every motherboard has "Windows drivers" for download where in Linux it's all part of the same kernel. But this bites linux in the face of BIOS bugs: it has to make the assumption that the BIOS follows the relevant standards. It's not that you can't do the work to make this happen on any given device, it's that no one is paying the teams of engineers to actually do the work for every device.

This article mentions that the kernel now has support for Microsoft Kinect. How so? It seems odd to support that in the core kernel...

  It's support for access to the video and IR sensors. http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=6612155a1dce344fb609c9487a879c693150ebb1 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6...
