dronus, thank you for reporting this and helping make Ubuntu better.

As per http://support.lenovo.com/us/en/products/Laptops-and-
netbooks/ThinkPad-T-Series-laptops/ThinkPad-T420s? an update to your
computer's buggy and outdated BIOS is available (1.39). If you update to
this following https://help.ubuntu.com/community/BIOSUpdate does it
change anything?

For more on BIOS updates and linux, please see
https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette
.

Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful. As well, you don't
have to create a new bug report.

Once the BIOS is updated, if the problem is still reproducible:
1) Please provide the output of the following terminal command (not perform an apport-collect):
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
2) Please make a comment specifically advising on if there was an improvement or not.
3) Please mark this report Status Confirmed. If it's not reproducible, please mark this as Invalid.

Thank you for your understanding.

Title:
  Removing EXT3 USB key while unmounting left system stuck

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  When ejecting and then removing an USB stick using an EXT3 fs in the
  short interval before it is completely unmounted, "umount" gets stuck
  at 100% CPU load. The process cannot be killed, even with signal 9
  (KILL).

  Any attempt to mount an storage device results in an error.

  Any USB device plugged afterwards is not mounted, the system would not enter standby and would stuck on reboot or shutdown. 
  Not shutting down or enter suspend may expose security risks, as encrypted filesystems may stay open and screen locks fail to lock.

  Despite this, the system works normally.
