If I connect my DVDRW device (iomega "SuperSlim DVD) via usb I get the following entries all the time in my /var/log/syslog:

They are identical down to every bit of hardware and operating environment, They've been reliably running Debian and Ubuntu Linux releases for years. There's something in the latest Ubuntu 10.04 server builds that has introduced a regression. They are used for heavy but sporadic CPU-bound work. Over the course of a day, the odds are that a singular server will experience a kernel. Over two days it's practically guaranteed. The kernel panic says: "sd 2:0:0:0 rejecting i/o to offline device" sd is the system drive and is most certainly online. A hard reboot fixes the matter for the following day or so.
