ubiquity Hangs on 12.04 alpha install

[Len Ovens]

On ubuntustudio 12.04 alpha 2 live install ubiquity hangs (visits la-la land) Says configuring system but there is no target disk activity. This seemed to happen when I switched to a console with control/alt/f4 to do a tail -F syslog to see what was happening. (being overly curious) There did seem to be can't get frame buffer errors during this time. I'm not sure if the best solution is to warn again accessing consoles or not have them running. However, when I install doing nothing else there is no problem.

At what point in time did you switch to a console and execute tail? I tried recreating this using tail -F syslog right after starting the installer and was able to complete an install successfully, however it did seem slower.

Incidentally, tail wouldn't show you anything on the console due to a different bug regarding inotify and overlayfs. So not seeing anything in the console is not indicative of the install not working.

New information. This may be caused by a wireless network connect
"cycling" as well. Wireless net work drops -> ubiquity is downloading and
hangs -> network comes back -> ubiquity doesn't.

I am not sure as I was switching back and forth. I had installed ok once
before, but felt that maybe it was the time I happened to switch.

I also had trouble using tail and so used less and then hit F. This did
work. The reason I thought it was the switching to console was that I saw
a message about not being able to access the "fb" which I thought might be
a frame buffer. However, I have since then never used the console again
while installing, but rather an xterm. Yet I have still had ubiquity
freeze on me. ubiquity was trying to download something at the time and
the logs showed a wireless reconnect as the last thing that happened. It
is possible this was what really happened the first time too.

I have been testing the 12.04 iso about once a day and having tow freezes
is not that bad. it is certainly not consistent and repeatable.

If there are specific ways I can test this for you let me know.
