    So stable kernels aren't so stable.
    What else is new?
    That's why I run Debian... Kernel 3.2. Totally dodged this bullet.

    Have fun with this one folks

    I managed to get a kernel panic even with squeeze (2.6.32), the bug affected every 2.6.x/3.x kernel version.
    This is to say I'm fine with stable releases, you can't simply expect zero bugs.

    Recently a change was made in ext4 in 2.6.32.y (used as many distributions' long-term support kernels) which broke GlusterFS:

    So it can and does happen... not very often, but yes.

    DA FUQ is wrong with the stable kernels ?

    data corruption on ext4 (again ?!)


    luckily I didn't check and update for 3.5.7 kernel yet since this is my main production box *argh*


    the more this happens the more I consider moving entirely to ZFS ...

    Here is a list of affected versions:

    • 3.4.14
    • 3.4.15
    • 3.5.7
    • 3.6.2
    • 3.6.3


    I have filed a bug in Gentoo's bug tracker for this issue:

    The Linux kernel developers let distributions worry about regression testing.

    Apparently Linus Torvalds is actually just a bot that collects together kernel patches, it doesn't bother to check or review any of them.

    When we see all those nasty emails from Linus, blasting crappy code, those are just computer-generated random messages designed to create buzz. In fact they just check it all in without looking at it.

    Nope, the kernel developers don't do regression testing, the hold back kernel releases because they are too hung over from their partying. Yeah, that's the ticket.

    Feel free to help. If you think you can read and understand in every detail hundred thousand lines of code you can safely replace Linus.

    Software has bugs. It is simply impossible to dodge them all. Just think about the notorious random number generator in debian some stable release ago....

    Just thank you the openness of linux, will hit only a very small fraction of linux users and most likely geeks and contributors
