[Virtual-pkg-base-maintainers] Bug#675621: base: system freeze after safely unmounting usb drive

[Sebastien P]

Package: base
Severity: critical
Justification: breaks the whole system

After clicking safely remove a usb hard drive (1Tera Western Digital extern
disc), when I physicly unplug the usb cable the system freeze instantly to a
black-dead screen with only the mouse pointer showing (but not moving).
The keyboard (caps lock and scroll lock) blinking, mouse have power but neither
are working.
System reboot if reset button pressed, start like it should and did show any
notifications.
Problem is reproductible.
I never experience this problem with previous debian version (dist-upgrade), I
recently made a fresh install of the current version.
I guess this may occur since last packages upgrades ?
I may run troubleshooting if guided.
