Comment 11 for bug 726131

Unfortunately the log is a bit sparse. Could you try:

 * At the hostname prompt, switch to Alt-F2, 'nano /lib/partman/lib/base.sh', and put 'set -x' on the first line
 * Continue installation until you reproduce the bug
 * Kill the partman-related processes that seem stalled, in order to flush logs
 * Post the logs again
