  • 2.6-series Linux kernel opinions

    Mainly out of boredom but with a strong dose of curiosity I built my first production 2.6.3 kernel today, also the first one I had built from this tree since the (then-disastrous) release-candidate 2.5-series. I have to say, I'm rather impressed with the results on the test system (2.4GHz P4 Northwood, i845 chipset, Slackware 9.1 as base OS).

    For an early-release kernel, the i845 support is notably better than under 2.4 - an odd sound glitch involving mp3 decompression is gone, and YUY2 video overlay support now works properly (tvtime is actually operational). Performance actually seems a bit snappier, too. Not that I've conducted extensive tests at this point - these are all just first-run observations.

    The new menuconfig system takes a bit of getting used to, but the new hierarchy means that options are laid out more logically than in past releases. One thing I did notice: no more prompting if you build a kernel that's too large to fit on a boot floppy, though the option is there to install the kernel to the floppy.

    I'm pretty impressed with it on the first run - it seems like modern hardware is supported much better than under 2.4. Obviously I'm running it on my semi-sacrificial desktop, so critical production-environment components like RAID support, SMP, 10Gbit interfaces, and hardcore routing haven't been tested. However, it looks like it could mature into a better-managed kernel series than 2.4 turned out to be.

    Anyone else care to weigh in? It'd be good to hear others' opinions on this.

    O(1) thread selection and the new VM are probably the two biggest advantages of 2.6 over 2.4.

    (of course, as a Solaris zea*cough* administrator, I feel the need to point out that Solaris's timeshare scheduler has had constant time thread selection for over half a decade)

      2.6 to me is alot faster then the privous kernel. I myself did a small talk on this at the last dc707 meeting, the notes can be found at it was mainly a install guide, but alot of the group has 2.6 up and running without to many problems. Security was a small factor but .3 seems to have taken care of it.
      I would like to meet a 1 to keep my 0 company.
