[Note to bug reporters: If you can, please always add
[email protected] to the CC lists of your reports, as that will
help to filter them out of the other LKML traffic. Also, if you report a
regression, please add '[regression]' or something similar to the subject.]
This message contains a list of some regressions from 2.6.25, for which there
are no fixes in the mainline I know of. If any of them have been fixed already,
please let me know.
If you know of any other unresolved regressions from 2.6.25, please let me know
either and I'll add them to the list. Also, please let me know if any of the
entries below are invalid.
Each entry from the list will be sent additionally in an automatic reply to
this message with CCs to the people involved in reporting and handling the
issue.

I'm up in the air with this one, i.g. one minute this message is
appearing, and then the next it's not.
If nobody else is catching this or seeing this happen, then I'll take
it as a .config problem on my part.

That hardly shows it.

As a short work around setting #define TCP_RTO_MAX ((unsigned)(120*HZ)) to
#define TCP_RTO_MAX ((unsigned)(60*HZ)) in include/net/tcp.h does
help, but the problem is still there.
After testing this setting out for a few days, I decided to revert it
back, so I don't mess my tcp packets up, and feel like an internet hog

Nothing much I can do to help. The URB is assigned in setup and is NULL
later. Nothing else I can find touches it.

No suprise about the pppd - that would be the usual usage of this driver.

I tried to reproduce it this morning with 2.6.26-rc7, but failed. So, it
seems gone (but this was an Eisenbug, so I am not certain).

there were a number of drivers/char/drm/ and drivers/char/agp/ fixes
merged into -rc7 which could have resolved this. Please keep an eye on
it nevertheless.

Is that just a kernel build option? (As I mentioned earlier, I'm not
much of a kernel hacker, I usually just run packaged kernels).

It is the module option "debug" for usb-serial.

I can confirm that this problem still happens in 2.6.26-rc8.
When the gps loose connection (probably due to faulty USB cabling), then
the kernel spits out numerous WARNINGs.
I'll try to reproduce with USB debugging later.

Your device is considered to have two ports but not enough endpoints.
Please provide the output of "lsusb -v"

This is odd. Your device shows one interface with one endpoint bulk and
bulk out respectively. Yet two ports are created. Odd.

OK. If you mean /dev/ttyUSB0 and /dev/ttyUSB1 are always both created
when the device is plugged in - yep. This is the case in the working
kernel too. From what I've seen in howtos and the like, this seems to be
the case for most such devices. Well, let me know what else you need
from me. :)

Now this is very hard to explain. From the code in 2.6.25 it is clear that
only ttyUSB0 will be created. Please verify that indeed you get ttyUSB0
and ttyUSB1 with the kernel working for you.

As far as I can tell somebody changed the ipaq driver in 2.6.26-rc6. I cannot
find the exact patch that did it in Greg's directory. As it causes a regression
here's a reversal.

It was changed by:
commit e1879b19b0abdb387e4aeb0b935a486cc75042fb
Author: Matthias Geissert <[email protected]>
Date: Thu Mar 6 22:00:33 2008 +0100
USB: ipaq: fix devices having more than one endpoint
The ipaq module supports devices with one endpoint only. Some devices,
e.g. Yakumo Delta 300, have more than one endpoint.
This patch fixes support for devices having up to 2 endpoints which used
to work on older kernel versions.

This is good.

This is fatal.
The patch I sent reverts only this part, so this issue is solved.

I wouldn't call that "magic":

These fields are removed by a later commit in 2.6.26... 8-)

Well, NUM_DONT_CARE is default, so it makes no difference, but a comment
would have been nice.

They were removed from struct usb_serial_driver in
include/linux/usb/serial.h since the checks they were used for caused
more problems than they solved.
But you are right that the effects of the removal are the same as
NUM_DONT_CARE.

It is possible I'm misremembering on that front. I will check.

I checked what you said with kernel 2.6.26 rc9. I set num_ports to 5. It
worked quite well until I tried to connect to a non-existing endpoint.
However, the problem is that the Yakumo Delta needs to connect to the 2nd
endpoint. You can connect to the first one but you don't get any data.
Is there any good way to tell the ipaq driver to use the 2nd endpoint? Maybe
one could provide a different struct usb_serial_driver ipaq_device depending
on the usb id or an option which tells the driver to use 2 endpoints.

If only these devices have a second input endpoint, we can detect that
in attach().
