Comment 54 for bug 966294

It never really hung for me. What happened was that the ubiquity tread used all the CPU it could get and start eating up all the memory. After almost an hour of unresponsiveness the last bit of memory and swap was gobbled up and the ubiquity thread was killed (by 'kswap0' or something with a similar name). After that the liveCD desktop would start.

It does feel like something hangs, but the machine is actually really busy (and unresponsive).

I don't have a backtrace or the bugged .iso to reproduce the bug, sorry.
