The error messages shown below are being emitted by my Fedora 13 kernel. In fact, I see the same messages on any kernel newer than 2.6.31.12 in Fedora 12, too. Does anyone have a suggestion about what the problem could be? Hardware is a Dell Latitude E6400 which has been updated to the latest A20 BIOS. I am using a Dell-branded docking station with this laptop about 99.99999% of the time. I've included some normal messages for context, then the error messages follow. I get thousands of these.
