“mounting root filesystems” bug won’t be fixed for Dapper. (fixed in Edgy)

Filed under: Uncategorized — ubuntudemon @ 10:28 pm

Scott James Remnant says on bug 6367 :

Officially marking as Rejected for dapper.

Here is the reasoning:

– We applied the “fix”, as planned, to the udev in Edgy Eft.

– While the fix corrected the problem described here, it caused new problems. Because it was a fundamental change to device ordering, it changed the order of other devices where more than one existed in the system — including other disks

– For Edgy this was not a problem, as the upgrade makes other changes that make device order non-important anyway

– These changes are too invasive for backporting to dapper

– This bug has a known workaround, which can be applied by the minority of users affected by it

– That workaround is preferable to causing far more working systems to cease functioning.

Scott thanks for this information. I will post this in the forum threads about this bug.



  1. Hi. I don’t mean to be rude, but could you possibly make the letter spacing less? It makes the content difficult to read. Thank you.

  3. sam : This is a free wordpress account. I don’t want to edit the html for 10 minutes with each of my posts.

    It’s possible to buy CSS support but wiki-like-language support is only possible if I host the website myselft AFAIK. I don’t want to pay for CSS support if I don’t get wiki-like-language support.

  4. f3ss : you can read more about this bug here : https://launchpad.net/distros/ubuntu/+source/udev/+bug/6367

    It’s only a small percentage of users who have this problem. If they backport the fix from Edgy other people will have problems. It’s not easily possible to backport a fix and guarantee it works for everyone.

  5. I encoutered this bug too when I installed Ubuntu on an additionnal hard disk that I put in the “bay” – drive of my DELL laptop.

  6. As I understand the bug, shouldn’t it affect _every_ user with more than one hard drive? With two or more drives, won’t it reverse the drive order and get confused with regard to the proper boot disk [at least for anyone upgrading]? Seems to me that “small percentage of users” would be an underestimate of the scope.

  7. This bug doesn’t effect everyone with two or more drives. It only affects people with certain hardware (combinations).

    The bug has to do with udev. For more information see :

  8. I’m wondering whether there’s more than one bug. Is it possible that I’m not having a udev issue? According to:
    udev is a userspace element.

    My problem goes away if I use the 2.6.12 kernel (at which point I have sound card issues).

    The reason I ask, is that I have pretty generic hardware: HP Pavilion a350n with an external USB hard drive. If the USB hard drive is attached during boot, it is mistaken for the boot drive.

  9. To me it sounds like the udev bug.

    If you still have doubts you could make a comment on the bug in launchpad.
