During startup hwclock.sh is run more then once. In rare cases they overlap causing the PC RTC to become non-functional. This is because the second copy of hwclock falls back to using IOPL and direct I/O instructions after it fails to open /dev/rtc (already owned by the first copy of hwclock). The RTC hardware is not designed for such uncontrolled access.
