Hello, Sorry I had to leave this for a few days ... Anyway I believe I have discovered where the problem lies. First things first, booting with kernel '3.16.0-43-generic' works OK.
The other thing I discovered (latest kernel) is that if my TV tuner is active the system won't boot. The light on the tuner goes out after the boot starts and the system hangs. When I power down and restart the light is out and will come on again after I see the 'ACPI PCC Probe failed starting version 219' and the system boots. If I disconnect the tuner from scratch before switching on the system boots OK with the latest kernel. This also explains why I noticed that it would boot OK after using Windows first as it switches the tuner off on shutdown / restart. So it looks like the problem is with the TV tuner or the driver more likely, but only with the latest kernel. Its a fairly old tuner - DVICO usb (AU version) - and all I did to install it was to download "http://www.linuxtv.org/downloads/firmware/dvb-usb-bluebird-01.fw" and copy to /lib/firmware. I use MeTV. Hopefully this helps. Again, any advice / tips much appreciated. Regards.
