Title:
  Ejecting external USB hard drive causes kernel panic

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  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?
