Okay. It indeed is not fixed. The "problem" with reproducing
it was due to the need to have proper timings -- if you connect
to the pty console "too soon" the bug wont be visible. It also
behaves slightly different in kvm and tcg (plain qemu) modes -
ie, it needs a bit different amount of time to wait before
connecting to the pty.
So finally, the patch I thought fixes that issue does actually
not fix it.
I did a git bisect run and determined a commit which went into
1.1.0 which introduces this bad behavour --
http://git.qemu.org/?p=qemu.git;h=67c5322d7000fd105a926eec44bc1765b7d70bdd
So I asked the author (in the thread mentioned on top of this
bugreport) for some help about this issue. Will see were it
wents to. Meanwhile you can just revert this commit - it is
quite small - so that your guests will start working fine.
Pity it isn't fixed - this means headaches for users continues,
and new upload is in order too, which means more coordination
with the release team is needed.
Thank you for your patience. Much apprecated!
