After the first oops generated by unplugging and replugging the drive, I
attempted to unmount the partition that was on that drive. That
generated another oops. Attempting to shutdown and restart hung the
machine and I had to hit the power switch.

Here it is:

 <1>Unable to handle kernel NULL pointer dereference at virtual address 00000044
