Bug Description
Binary package hint: ubiquity
Occurs when trying to install Ubuntu from a LiveCD, for both 8.04.1 and 8.10 Alpha3. Boot from LiveCD, initiate install, choose "use entire disk" option. The installation proceeds as expected, until system freezes (cursor not responding, no noticeable hard-disk or CD activity) at the "Copying Files" stage. Almost always occurs with progress bar at 22-23%, although once I got as far as 34%.
However, the installation of 7.10 from a LiveCD completes with no problems.
The CDs I used were all burned at the lowest speed, and afterwards checked for defects. I have tried booting with acpi=off option, with same results.
A forum thread devoted to a similar problem can be seen at: http://
The computer I am using is Averatec 3255 laptop (I needed to modify Monitor section of xorg.conf slightly before I could start X, though)
WORKAROUND: Ubuntu 8.10 livecd:
1) Boot with "break=top" option
2) At BusyBox prompt, execute
echo 'options libata dma=0' >> /etc/modprobe.
3) Ctrl-D, and continue install as usual
The problem was due to my CD drive, QSI SBW-242, causing occasional system freezes, when used with UDMA/33. (Actually, forcing UDMA/25 or 16 makes the freezes occur much more often). So, adding 'options libata force=2.00:pio4' instead, also worked for me.
Still occurs for 8.10 Alpha5. Occurs when booting with "all_generic_ide" option, as well.
