I got around to stress-testing the bug (100 baud - reading pulse
trains from things like an IR remote from an Arduino).
Works perfectly now. I haven't had a single IO error or other crash (no
overrun either, but it is hard to overrun a megabaud).

The "selective update" portion in the wiki apparently doesn't quite work - I
entered the information as it said and started aptitude. I also set a tic-mark

Ah - the "preferences" text in the selective part doesn't work, at least not if

I've not found any newer kernel using jaunty-proposed, and whatever I
have now still has the problem occasionally.
Is the -15 supposed to fix everything?
(Ryan - could you try a loopback and copy a massive file like in my post
#13)
Also what should the kernel display with uname -a?
Mine says:

> 2009 i686 GNU/Linux
That is not the proposed kernel. Proposed would have a #51 after
generic.

So far, things are looking good with this kernel and my FT232RL. I will
advise if the problem doesn't stay fixed :-)
Thanks!

Rereading the earlier messages, if a linux-kernel or such comes out
later today in -proposed I will try it and get back.

Does not fix this. It sounds like my problem, but only happens when the buffer
overruns.
I will try one of the 2.6.29 kernels and/or Karmic when I get a chance.
For example, using

Accepted linux into jaunty-proposed, the package will build now and be

Yes, the patch in question was part of 2.6.29, so Karmic should work.

Thanks Stefan, waiting for -15.50. So did I understand correctly that
any Karmic kernel would already have this fix? Might give a try on a
laptop.

It would be in the next proposed kernel (-15.50). Unfortunately it is still
waiting to get accepted into proposed.

In what kernel is this fix included? I run 2.6.28-15 on Jaunty and have
problems seeing anything from /dev/ttyUSB0 using the same receiver:

OK, there's no such thing as 2.6.28-stable anymore :) I'll send to the
Ubuntu kernel team instead.

I sent the patch to sta...@kernel.org, so hopefully it will get included
in 2.6.28.11. I assume it will make its way into Ubuntu after that?

You're perfectly right, any recent mainline > 2.6.28 already contains the fix.
I tried with http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.29.5/ and our
ftdi is fine again. How do you manage this kind of issue at Canonical ? You

Replacing 'return;' with 'goto out;' appears to be the exact solution
upstream has chosen. Please try a more recent kernel to confirm, perhaps
something from the mainline vanilla series at http://kernel.ubuntu.com
