Hello Joseph, Thanks for responding.
Sadly it didn't work either first up. Its very strange because once I go through initial hiccups it boots normally on the latest (and previous - 3.19.0-23-generic) kernels. What is even more crazy (and I'm loath to even say this because it sounds so idiotic) is that it appears to only happen from a completely cold start - as in switch on at the wall switch. These are the steps:- 1. Switch on at wall power (note this also starts my modem and lights up a USB TV tuner I have connected) 2. Switch PC on 3. Select Ubuntu (its a dual boot) and get the hanging problem 4. Power down the PC (holding the PC power switch) 5. Switch PC on again 6. Select Ubuntu and get the 'ACPI PCC Probe failed' message and the PC boots 7. After this I can 'shutdown' or 'restart' with no more problems Another item of interest is that it worked OK if I start up Windows first and then restart - I think. I'll confirm this tomorrow as I've done so many combinations now I'm a little hazy on that one.
