Tried this but it didn't make any difference.  I also tried uninstalling 
the frkit powernow driver completely, and still I see exactly the same 
timeouts.  I also tried updating /etc/power.conf to disable autopm and 
run pmconfig (and rebooted) just in case but still no joy.

Thanks for the suggestions, but we are stuck again and I have no idea 
how to debug this part of the system.  Any hints ?
