I was scanning the regressions list and noticed that I could reproduce
this bug.

So I bisected it to commit 335f8514f200e63d689113d29cb7253a5c282967
("tty: Bring the usb tty port structure into more use"), from Alan
Cox.

I did not double check if reverting it from -rc4 fixes the issue,
but I noticed that this patch touches drivers/usb/serial/option.c, which
is the driver I used to test this problem.

If there is anything else I can do (give more info, test patches etc),
please let me know.

It doesn't revert cleanly from -rc4, but I solved the conflicts in
option.c and usb-serial.c (I wanted to learn how to do it)
and the problem gets fixed indeed.

Are you certain this really is a regression? Under 2.6.30 and 2.6.27
the same thing happened if I unplugged a USB serial device while it was
in use.

Can you check whether the device is still being used when you unplug
it? For instance, is there still a pppd process trying to communicate
with the device? If there is, what happens if you kill all the
processes using the serial device before you unplug it?

In short, it seems likely that this is not new behavior but rather the
way usb-serial has worked all along.

I checked and rechecked that the pppd process is already dead by the
time I unplug the device. However, the minor number did not increase
if I unplugged the device without using it beforehand, as expected.

I didn't experience this problem with 2.6.30: my ppp script was
hardwired to use ttyUSB0 and it always worked. Now with 2.6.31-rc3 it
does not, as the device node keeps changing.

I'll test this with opening ttyUSB directly from the shell, instead of
via pppd, and report back whether it makes a difference.

I wouldn't expect it to.

In the ppp case you have this occuring on an unplug

USB layer
unplug
hangup tty
PPPD
SIGHUP
ouch
log stuff
close down

However at the same time that PPPD is logging stuff and closing down th
USB layer is going to see the replug if you just unplug/replug quickly
and in that case you will get ttyUSB1. That aspect is timing dependant.

If everything has closed down and given the port back before you replug
it you should get ttyUSB0 again.

Ok, so how long is "quickly" here? During bisection I typically waited ~30 secs
and there was no pppd listed on 'ps aux' when I reconnected it.

#

I don't know what to say. I believe in you, of course, but I am not
seeing what you expect. For example, after sending the last email
I unplugged it and went back to work until I read this reply of
yours. So I did this,

[***@Pilar:5-pts-tree-level]$ ls /dev/ttyU*
ls: cannot access /dev/ttyU*: No such file or directory

which is OK, because the stick was not plugged in all this time. So
then I plugged it and got this,

[***@Pilar:5-pts-tree-level]$ ls /dev/ttyU*
/dev/ttyUSB1 /dev/ttyUSB2

And it took a lot longer than 30 secs this time, more than 5 minutes
for sure (and I don't see anything suspect in the output of 'ps aux').

And the fact that is, reverting your commit made things work under
the same testing conditions.

Do you have any suggestions as to what I should do between unplugging
and plugging it back?

My original report is about unplugging the USB servial device *after*

Yes, I did this:

1) plug the surfstick
2) connect to the internert (with draknetcenter)
3) disconnect (and wait a bit)
4) unplug the surfstick (and wait a bit)

Then when I plug it again, the devices created are /dev/ttyUSB{1,2} instead
of /dev/ttyUSB{0,1}.

That breaks 'draknetcenter', because if I try to connect again it
says that /dev/ttyUSB0 can not be found.

And during the bisection, for the commits which were marked "good", there
was no problem to reconnect and 'draknetcenter' was happy (although perhaps
it should not be so dependent on /dev/tttyUSB0 only, but that is another
story).

Yes. I have nuked the odd stuff in my rc.local file, and rebuilt this kernel
with several mods that I thought might be related, but it is still failing in
the same manner. The error messages (apparently from lp:, but long after cups
has been started) do NOT make it to the messages log file either, so its
totally blown up at that point.

Note, that this is a regression from 2.6 31-rc3, which works fine. So the
thing shouldn't be that hard to find. But in looking over the changelog,
nothing obviously reaches out and grabs me.

I'm not really equipt to do a bisect here either, my git from F10 is at least
2 versions old now. And I'm crippled by a way too small /boot partition which
can't hold more than 12-14 kernels. The disk partitioning tool in F10 is
nothing short of fscking broken IMO. But fedora isn't interested in that
either, cuz its existed since at least Fedora 2. Here, fedora is on its way
out, 64 bit mandriva sure looks nice. And DiskDrake Just Works(TM).

Thanks Rafael, I thought it was being ignored.

The following bug entry is on the current list of known regressions
from 2.6.30. Please verify if it still should be listed and let me know
(either way).

Yes. I have nuked the odd stuff in my rc.local file, and rebuilt this kernel
with several mods that I thought might be related, but it is still failing in
the same manner. The error messages (apparently from lp:, but long after cups
has been started) do NOT make it to the messages log file either, so its
totally blown up at that point.
Note, that this is a regression from 2.6 31-rc3, which works fine. So the
thing shouldn't be that hard to find. But in looking over the changelog,
nothing obviously reaches out and grabs me.
I'm not really equipt to do a bisect here either, my git from F10 is at least
2 versions old now. And I'm crippled by a way too small /boot partition which
can't hold more than 12-14 kernels. The disk partitioning tool in F10 is
nothing short of fscking broken IMO. But fedora isn't interested in that
either, cuz its existed since at least Fedora 2. Here, fedora is on its way
out, 64 bit mandriva sure looks nice. And DiskDrake Just Works(TM).
Thanks Rafael, I thought it was being ignored.

You're welcome, thanks for the update.

(either way).

Now I'm not sure if it's a regression, because it happens not every
boot. Maybe I just noticed it after 2.6.30

jiri, I found the place via extra printk messages added to the i8042.c

in function i8042_check_aux(), when touchpad detecting fail, it fall
into following error path:

if (wait_for_completion_timeout(&i8042_aux_irq_delivered,
msecs_to_jiffies(250)) =3D=3D 0=
) { [snip] }

so maybe the timeout value need to be increased? I try redo the
i8042_setup_aux after it fails, it fixes the problem indeed, which one
is the proper fix do you think? If it's the right fix I can post the
patch.

I probably wasn't clear enough in my last mail about this one. The
errors have always been present, we just report them now. I think this
particular one is harmless, but we should still try to fix it (now that
we have more data about it).

This patch hasn't found its way into Linus' tree yet, so it's definitely

This bug should remain open, although we are, I think, getting closer
to the cause, which seems to be related to some interaction between
the rt61 driver and mac80211 power saving.

There is definitely a regression, in that it doesn't work without
config changes to Myth. This is due to the new way that firmware uploads
are implemented in xc5000: slower, and more often than before.

Post by Rafael J. Wysocki
3. In mythtv-setup -> CaptureCards -> DVB:1 -> RecordingOptions
there is a tickbox for "Open DVB Card on Demand". It was ticked,
so I un-ticked that box. Everything now works!
When that tickbox was selected, the xc5000 took five (5) seconds to "open",
as it did the firmware upload every time. This appeared to exceed some
timeout inside myth.
With the tickbox NOT ticked, myth just opens the tuner once at startup,
and keeps it open, so no more delay when it wants to use it.

Dunno what to say about this one.

That's presumably correct, as rc4 (on-tag at last git pull) resolved it.

Just updated the bug.

(I didn't know whether CODE_FIX or PATCH_ALREADY_AVAILABLE was correct, and
the status link is to the generic bugzilla resolutions, so not much help. I
picked CODE_FIX. I guess that's the next bug I file, on bugzilla.kernel.org

For the bugs on the regression lists CODE_FIX is correct if the fix has been
merged by Linus or the problem has been confirmed not to be present in the
Linus' tree any more. In wich case the bug should be marked as CLOSED.
