Thanks again James. The md5sum was OK so I reformatted the USB stick and tried again - and no error. I have done this so many times before on XO-1 but never seen this. So the first time I tried on XO 1.5 it happened. I must remember the old adage, if the car doesn't start maybe it has no petrol...

Please run the heat spreader test on this unit: ok test /switches If the heat spreader does not contact the CPU properly, the temperature can rise too much during installation. If the temperature is too high, the CPU can pause, or make mistakes. Significant gaps, blocks staying gray, are normal, and nothing to worry about. These blocks don't need to be written, so the .zd file does not write to them. This saves on downloads. The error "Wrong expanded data length" means that the file was not correct on the USB drive, or the USB drive could not be read. The task was aborted. Things you can try: * check the file using md5sum, see http://wiki.laptop.org/go/Download#Verifying * try a different USB drive, * don't use a USB hub, * disconnect any other USB devices, * try a different port on the laptop, * upgrade the firmware; you are using Q3C07, but Q3C08 contains a fix for USB drives with embedded hubs, and Q3C13 has a fix for USB drives with unusual partitioning. Q3C15 is the latest version. That the XO starts up OK afterwards is not a valid test, since it would likely have the same build already installed. No logs are kept of firmware operations, so you won't find any evidence; you have to repeat the problem and gather data that way. -- James Cameron http://quozl.linux.org.au/ _______________________________________________ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
