Comment 1 for bug 365702

Please run the installer again in debug mode (`ubiquity -d` from a terminal window) and attach /var/log/syslog, /var/log/partman, and /var/log/installer/debug. We'll need the partman log file to get a better idea of what's going wrong, as the device nodes are created independent of the installer, so the bug is likely to be higher up than that.

Thanks!
