I too receive this error - although not during boot up. It occurs for me when I attempt to use the internet, and after about a second or so, it cuts out. Ping manages to get through, but anything more demanding fails. Once it fails - NOTHING gets through. This has stopped my upgrading to 2.6.17 kernel in Ubuntu, although I am using the latest in everything else. I might also comment the nVidia drivers also fail to run before AND after this occurs.
The actual error message on the command line is (or something similar, as I attempt to read my scrawled writing): [ 437.549280] sr 0:0:3:0: rejected i/o to offline device I will restart my computer now, in order that I might send you the /var/log/dmesg and /var/log/udev files.
