Public bug reported:

Binary package hint: linux-source-2.6.22

Rather than re-opening bug #16345, opening a new bug (since was fixed for 26658 
poster in 2.6.15...) - I left some comments in #16345 originally...
https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.15/+bug/16345

Exactly the same problem as #16345 with Feisty (fully updated), 2.6.22
kernel and a Dell Optiplex 745 desktop machine.

hwclock will not work with the default /dev/rtc. It works with the
--directisa option, or by replacing rtc with genrtc manually. I would
suspect other Dell desktops may have the same issue?

uname -r

lsmod | grep rtc
rtc                    13208  0

Let me know if I can provide further diagnostics.

Thanks.
