    <link>http://brainstorm.ubuntu.com/item/5583/</link>
    <description><![CDATA[1. There are deeply invasive performance/scalability/latency fixes for CFS regressions (vs. 2.6.24) in the 2.6.25 tree.  These fixes are too invasive to be ported to the 2.6.24 kernel without significant risk.<br /><br />2. Many of the driver updates/new drivers in the kernel-ubuntu package are merged into upstream as of 2.6.25. (This is always true, but the smaller the delta against upstream the better on release day).<br /><br />3. Fedora 9 is based on 2.6.25 which means that key RH kernel developers are aggressively working to get the feature and performance/scalability regressions vs. 2.6.18 & 22 fixed.<br /><br />4. The kgdb patch will probably be merged at the start of the 2.6.26 cycle which means the delta vs. 2.6.25 kernel should be pretty manageable.  This would be really valuable from an LTS ongoing perspective.<br /><br />5. The RT patch will be better maintained (and smaller) against 2.6.25. (see #3)<br /><br />6. Better virtualization and SELinux support (see #3).<br /><br />Given the life-cycle of an LTS release (especially this one which will finally have a meaningful chance to enter the data center) these considerations are especially important.  <br /><br />Obviously 2.6.25 would have to be in addition to 2.6.24 for the Hardy 8.04 LTS release time-frame, but it does allow the aforementioned benefits to be propagated forward.<br />

  <description><![CDATA[This is not to suggest dropping the 2.6.24 development on the floor (it's too late in the cycle for that), but rather to get a 2.6.25 kernel into universe or as an alternate in base (like RT or SELinux support).]]></description>

  <description><![CDATA[Ask Linux how long 2.6.25 is going to take. Hardy is LTS. And LTS was moved to June last time. Maybe this time again. If important software is delayed, then this is a good reason. And I do think the kernel is important enough.<br /><br />RH pays lots of important kernel hackers. If 2.6.25 is going to be the base of a Fedora release, then Ubuntu might save a lot work on the kernel in the future by taking that route.]]></description>

  <description><![CDATA[FWIW There will probably be at most one more RC for 2.6.25 before the final release.  Excluding 2.6.23 & 2.6.24 which suffered from the addition of a new CPU scheduler Linus almost always releases after RC6 or RC7. Note Feisty was almost perfectly aligned with the _very_ stable 2.6.22 kernel.  2.6.24 is more stable today, but in the long run certain ABI/API changes in the 2.6.25 cycle might make it a better baseline for an LTS release.  Ingo Molnar, Greg KH, and Jeff Garzik (RH staffers) all seem to have worked really hard to make the 2.6.25 kernel free of corner cases and ABI deficiencies relative to the old scheduler and driver infrastructure they maintain.]]></description>

  <description><![CDATA[i've been playing about with the beta of hardy, thinking i could help with bug reporting. the trouble is, i haven't found any bugs yet. for this reason i think that hardy is going to be really good. anything that would rock the boat at this stage should be considered very carefully. <br /><br />having said that, your list of advantages for the funky weasel kernel is very interesting, so it would be great if 2.6.25 were available in the repositories<br />]]></description>

  <title>Comment from jordi1983</title>
  <description><![CDATA[If we consider that this release will be installed in enterprise production desktops and servers, it is mandatory to have the latest and/or better kernel out there and the same for all the drivers that will be released after Hardy and most important applications.<br /><br />Like it happen with Dapper if Canonical only does security updates and not new version updates not only for the kernel but also for drivers, firefox, openoffice, gimp, etc... then it's silly to maintain a distro for three and five years.<br /><br />Think about it, how many people or companies use dapper today?<br /><br />So it's very important to make available the 2.6.25 kernel, but also the new versions that as time goes by will be released if they improve the old one.<br /><br />Remember, we are talking about a LONG TIME support release.]]></description>

  <description><![CDATA[Kernel 2.6.25 needs to come in. Like that of many others my WLAN chip can't connect to encrypted networks on Hardy because of the whole "ndiswrapper and symbols"-dilemma. This is supposed to be fixed in 2.6.25. I can live without wireless temporarily, but not for three to five years. ]]></description>

  <title>Comment from callegar</title>
  <description><![CDATA[Yes, please.<br /><br />2.6.24 has very big problems leading to lockups and hard freezes on many computers.<br />For reference, see the long discussion on the forums at http://ohioloco.ubuntuforums.org/showthread.php?t=768200<br />or http://ph.ubuntuforums.com/showthread.php?s=f0a7e1e71fc8753bf83472f31604107e&t=765510<br /> or the many bug reports such as https://bugs.launchpad.net/ubuntu/+source/linux/+bug/204996 and the tens duplicate thereof.<br /><br />2.6.25 is said not to have such issues.<br /><br />Also, 2.6.25 is the fedora 9 kernel.  Using the same kernel as fedora would mean that bugs can be fixed faster, because there is a larger userbase and no need to identify the precise bits causing problems to backport solutions to a former kernel. So, even if 2.6.25 could not fix right now the above bug, moving to it would be a win anyway.<br /><br />Wasn't the Ubuntu founder the big supporter of "distribution syncronisation"? This is a situation where using the same kernel version could really help.<br /><br />So, please make 2.6.25 available for hardy asap.]]></description>
