i am not really sure what's happening here, trying to rip a cd with
grip after a while i get the following:

and then this last message is repeated over and over again. rebooting
"fixes" the problem. i am not sure this is only a cdrom problem or has
something to do with the filesystem (reiserfs). the computer is an ibm
thinkpad t40 laptop (but this also happened on my desktop at work with
a different cd so its probably not the cdrom drive going bad).
