So, what changed between before and now? Did you upgrade/reinstall? What 
build are you running?
And is it an external USB drive? It should not be attaching to ohci, but 
to ehci. pull the disk out, note the last bunch of error messages 
reinsert it and get a fresh set of messages that occur on insertion of 
the disk. Don't bother much about the interrupt sharing messages.
