    Buffer i/o error on device loop0 logical block xxxxxx

    Have been receiving this error on reboot with Vista/WUBI 9.10 Karmic since Alpha stages.
    Sometimes if fsck before rebooting it will reboot without interruption, sometimes.
    Uninstalled [lupin-support] and seems to be rebooting fine without fsck before every reboot. Do not know consequences of removal of [lupin-support].
    Anyone that knows anything about this I would appreciate your input.

    Can have 10 or more Buffer I/O error on device loop0 logical block xxxxxxx
    at any given reboot and need to alt/sys rq/b to reboot.

    [lupin-support] being WUBI support function is it detrimental in long run???
    2.28.1 (Ubuntu 2009-10-23)

    I'm having the same thing happen with 2 notebooks. vistas/9.10 beta and xp/9.10 beta (both installed from 9.04 wubi installer). Boots fines, but hangs on shutdown/reboot with errors. I'm also just using generic drivers. Doesn't do it on my box with just it installed. I forced fsck to run last night and it found nothing, I've forced scandisk to run on the the other side and found nothing. Freaked me out first time I saw it cause I'd just reloaded one from a corrupt file system.

    Not a lot of action here just the two of us. If I find anything out I will let you know.

    I have reinstalled [lupin-support] and will fsck and sudo reboot from Terminal until
    fixed. Found same problem back in 2008 in launchpad but nothing more recent. I am
    sure there are a lot of us out there.

    I myself have a 80 year old father who lives with me who needs his Windows. I just got
    him started a few years ago and Linux gives him the Willy's. He deserves what he wants to
    use so I dual boot. WUBI does have a value. Got me started, my next purchase will be laptop with only Linux. For now will try to get this Vista/Ubuntu WUBI dual boot in order.

    Same for me
    I upgraded to ubuntu 9.10 from a WUBI install and the computer does that on shutdown...

    I am having look at it.

    I'm having what appears to be the same issue too. Ubuntu 9.04 installed via Wubi on XP never hand any issues rebooting. Then I did an update to 9.10 beta via "update-manager -d" and now I often (but now always) get buffer i/o errors on device loop0 when rebooting. I got them to mostly go away by stopping BOINC from starting up, but they still happen, seeming randomly. I found this lengthy bug report from last year: https://bugs.launchpad.net/wubi/8.04/+bug/204133 . However, I'm having trouble making a whole lot of sense of it. I'm not new to linux, but I'm no guru either.

    Same problem here... seems to be random.

    I've just upgraded to Ubunto 9.10 after using a 9.04 installation from Wubi. Never had this problem with Jaunty, only appeared after upgrading to Karmic.

    Upgrade Oct. 26th 2009 Karmic 9.10 rc of [lupin-support] seems to have fixed issue.

    Check Synaptic to make sure you have .27 the new upgrade from .25

    So far so good.

    I upgraded lupin-support to .27, but I'm still getting the loop0 buffer errors. When I'm getting the errors, if I hit ctrl-alt-del, it'll abandon the journaling and the loop0 errors will keep coming. But, if I hit C-A-D after that, it says something about hwclock-save being aborted. Every C-A-D after that gives me the same message about hwclock-save. Is that what everyone else is seeing? Did simply upgrading lupin-support fix everyone else's problem? Ugh, my next Ubuntu install will not be through Wubi!

    Updating lupin-support to .27 did not solve the problem here... I'm geting the same behaviour as poo706
