I have recently helped out an installation of a Dell personal workstation (I believe it's an Optiplex desktop) and have been bitten by the same issue (kernel will freeze when loading with a message related to the RTC driver)
After changing /etc/init.d/hwclock{,first}.sh and /usr/sbin/tzsetup so that all /sbin/hwclock calls used --directisa the bug would go away. This seems to be an issue in the 2.6 kernels, however (the installer used the 2.6.8 kernel image, I later installed the 2.6.9 but did not try wether it would break with the hwclock calls) There seems to be a number of bugs open related to hwclock in util-linux related to this, even though it's a kernel issue, maybe hwclock could work around it (See #186973, #22478, #127975, #22478) Regards Javier
