More USB woes

[Thomas Milne]

I'm starting to get worried....

Today I shut down my computer to get the dust out, and when I booted
back up, my big external drive would not mount (panic), so again I
looked at /var/log/messages to see what I could see. Eventually it did
mount (whew!), but this is what I saw in messages:

Is there something wrong with my computer? I don't get this with my
iPod when I plug it in, and now the USB key that was not working
previously this week (see other USB thread) now is working, no errors
in messages.
