Re: Fedora 9 /dev/rtc missing

I have a dual boot Fedora 9 / Win XP Pro box.  I notice that when I
boot to fedora my time is wrong and "System Clock Uses UTC" is still
checked even though I unchecked it at install time.  When attempting
to clear the "UTC" check box and reset the time with
system-config-date I get the following error "Failed to synchronize
hardware clock.  This may be because there is no hardware clock
accessible, e.g. when running in a virtualized environment".  I am not
running in a virtualized environment so I checked the output of the
following:

  hwclock --debug --show

and got the following response

  hwclock from util-linux-ng 2.13.1
  hwclock: Open of /dev/rtc failed, errno=2: No such file or directory.
  No usable clock interface found.
  Cannot access the Hardware Clock via any known method.

I ran dmesg | grep /dev/rtc and got no hits, I booted hit del to enter
setup and checked the cmos menu in order to look at the clock and it
seemed right so I don't think the battery has failed.

Let me start by saying that XP has an option to run the clock in UTC, and that you would have been happier to run your hardware clock that way. Having the hardware clock reset seems to leads to other learning experiences.

It sounds as if your hardware clock is simply not usable by the kernel drivers. However, if you boot and get the system starting at nearly the right time, then it's likely that your hardware is being read. In /var/log/messages, when you boot do the messages have the right time? If so some source of the clock was found.
