Resolved: hwclock hangs on DELL 4700
I've finally cracked the problem of hwclock hanging during startup and locking hard during shutdown on DELL Dimension 4700's running Ubuntu. You need to add --directisa to tzsetup, hwclock.sh and hwclockfirst.sh. I've put a more detailed answer on this page. Yay, one more bug down. Don't know whether this is a bug that needs to be logged against Warty or not but I'm happy it's resolved.
