I weekly backup a virtual machine directory to an external USB hard drive. The directory contains several small files and a single image file whose size is about 50 gigabytes. After the directory has been copied, I eject the USB drive. This normally works as expected. However, on several occasions, the act of ejecting the external USB hard drive has resulted in a system crash. No information appears in /var/crash. No desktop password dialog appears. The complete screens fills with a crash report. I do not see any option to save this crash report and therefore have attached two photographs. Please note, both photographs of are of the same crash... One photograph might display a little more information than the other. Once the screen has filled with the crash report, I am not able to get any response with <control>C, <escape>, or <enter>. The only way I have found to proceed, is to power down the system and reboot.
I would like to be able to submit a crash report so that this problem can be properly diagnosed. What changes can I make that will provide more information to help you diagnose this problem?
