Comment 0 for bug 468589

I recently upgraded to ubuntu 9.10, Karmic Koala, and I discovered that I am unable to shut down or reboot. When I select shut down, Karmic starts the process and then hangs. What I get on my screen is this:

*Stopping Kernel Oops catching service kerneloops
*Shutting down ALSA...
*Asking all remaining processes to terminate...
*Deconfiguring network interfaces...
*Deactivating swap...
[ 171.180168] Buffer I/O error on device loop0, logical block 3834127
[ 171.180116] Buffer I/O error on device loop0, logical block 3856120
_

Then a blinking curser. I have no alternative at this point than to manually press the power button to shut down. I will follow this thread so please tell me if you require more information
