  Hibernate with fwts will cause hwclock command to time out

Status in “linux” package in Ubuntu:

Bug description:
  This issue was found in bug 1327075
  If you hibernate a system with fwts, and run the hwclock command, the hwclock command will complain that it was unable to access /dev/rtc, you have to reboot the system to have it back to normal.

  It can be easily reproduced.
