Comment 44 for bug 793796

I just saw this bug last night after upgrading to the 2.6.38-10.46 kernel on Natty. For me it *appears* to manifest as a panic talking to my DVD-ROM, after I had done some I/O to a USB device and ejected it (I used the nautilus "safely remove device" on the USB stick). The panic occurred several hours later. The panic wasn't recorded in my logs, but some I/O errors immediately prior to the panic were (attached). Note that when this happened the computer was idle, and the DVD-ROM having the I/O errors was not used *at all*. (there's not even a disc in the drive). There is another disk on the same PATA bus that should have had I/O though.

Also, I'd like to offer my kudos to steubens and Herton, you guys are doing a great job of communicating and isolating the problem with the kernel bisections (which I know is tedious). I've had some argumentative encounters on launchpad, but you guys are doing it right! Great job!
