Does Ubuntu 12.10 really ship with 3.5.0? Not any more recent

Some questions:

 - Are you seeing the same issue with 3.6.x?
 - If you can reproduce this issue, could you paste the messages in
dmesg when this happens? Do they resemble to the list corruption that
was reported?
 - Do you see the same problem with 3.4?
 - Are you able to apply the patch Alan Stern posted in this thread earlier?

We should really sort this out, but I unfortunately lack a system or
setup that shows the bug.


Thanks,
Daniel
