    Re: Buffer i/o error on device loop0 logical block xxxxxx

    I'm glad I'm not the only one. I was starting to think I had a unique problem. Even though it's the beta, I find it odd that I'm not seeing anything else about this issue around the net. This seems to be a problem with an earlier version of Ubuntu installed via Wubi, then upgraded to 9.10. I would think there would be a lot more of us.

    I upgraded 9.04 to 9.10 beta rc and keep getting error messages upon reboot or shutdown. Only works by using power button. Boots up fine. Updated lupin as adviced in this forum but still have same problem. This never happened with 9.04 Will release on 10/29/09 be the same???

    Headmower, did you install 9.04 with Wubi as well? If I remember right, I installed 8.10 with Wubi, then upgraded to 9.04 beta, then upgraded to 9.04, then upgraded to 9.10 beta, which is where my problems started.

    The issue is not solved so far, so the topic should be edited...

    I've started looking at hwclock-save that's being executed during shutdown/ reboot. When things hang and I eventually hit ctrl-alt-delete, hwclock-save is what's being aborted, over and over again every time I hit C-A-D. I'm still not fully understanding exactly what hwclock even does or if I really need it or not. Just for grins, I thought I'd try to disable hwclock-save that's executed during shutdown (but not hwclock that's executed during startup). After figuring out that the new-to-Karmic Upstart was handling the execution of hwclock and hwclock-save, I moved hwclock-save.conf from /etc/init to a temp folder. The first reboot test was successful! I'm not going to call it a complete success at this point because I've been tricked several times already with this issue. I finally noticed that I have successful reboots when Ubuntu has only been up and running for a few minutes. But after a little bit of use for 15-30 minutes, I'd get the shutdown hang every time (I'm pretty sure). The successful reboot after taking out hwclock-save was after about 30 minutes of use. I'll try throughout the night and report back later.

    Never mind, jumped the gun on that one. The two following reboots hung. However, the hwclock-save messages didn't come up after hitting C-A-D this time. In fact, hitting C-A-D brought up nothing at all this time. Does anyone know specifically which shutdown job is the one hanging?
