Sometimes when trying to print big jobs on a HP LJ 1022 it happens that all
processes accessing USB get stuck in D state. I captured the following relevant
stack traces, but apparently this does not include kernel threads (there was
another "khubd" stuck):

This _may_ have something to do with a flaky USB 2.0 hub/multi-card reader
combo (which sometimes disconnects, then immediately re-connects) on the same
USB 2.0 root hub as the printer. Unfortunately I don't see in the log whether
such an event has occurred at the time the print job started.
===============================================================================
From: Alan Cox <alan@lxorguk.ukuu.org.uk>

I've had a couple of almost identical traces here. In my case I also have a hub
which comes and goes as it is part of the monitor and when the monitor goes
into deep sleep it turns off [*].

[*] and yes if you plug your keyboard and mouse into the hub you realise
the designer wasn't thinking.
Comment 1 Alan Stern 2005-09-30 19:26:28 UTC
Unfortunately the khubd process is the important one here.  It's probably hung
somewhere in the printer driver's disconnect routine.  If you can get another
stack trace that includes it, please post it here.

It also wouldn't hurt if you turned on USB verbose debugging in the kernel
configuration (CONFIG_USB_DEBUG) and included the dmesg log.
Comment 2 Greg Kroah-Hartman 2005-11-14 21:43:00 UTC
Does this work properly now with 2.6.14?
Comment 3 Olaf Titz 2005-11-19 12:39:10 UTC
Still the same error in 2.6.14.2.
There is a khubd involved, but I can't get SysRQ to show its trace (is there any
other means to do this?)
Comment 4 Alan Stern 2005-11-19 18:04:09 UTC
Probably the stack trace is overflowing your kernel's log buffer.  You can
increase the size of the buffer by changing the Kernal hacking -> Kernel log
buffer size entry in the configuration.
Comment 5 Greg Kroah-Hartman 2006-03-06 10:26:55 UTC
Still an issue in 2.6.16-rc5?
Comment 6 Olaf Titz 2006-06-24 03:13:17 UTC
I can easily reproduce this (or something similar) still in 2.6.17.1.
Simply connect a highspeed storage device to the flaky hub and copy lots of
stuff to it. After some time, the hub disconnects and the whole USB subsystem is
blocked.
(Looks like this is not the printer but transfer of huge amounts of data which
is causing the problem.)

These are the last log entries when this happens:

And here are stack traces of all relevant processes, hope I've included all
kernel threads:

Comment 7 Alan Stern 2006-06-26 08:14:34 UTC
This looks like a duplicate of bug #6374.  The original problem as reported by 
 crazy@wi.rr.com, that is, not the comments added later by other people
describing completely different problems.  (Or maybe, since the number is
higher, that bug is a duplicate of this one.)

Something seems to goes wrong with certain EHCI controllers, causing
ehci_endpoint_disable() to hang.  A experimental patch was attached to the other
report, but it didn't seem to help.  Maybe you should try it just to see what
happens.
Comment 8 Olaf Titz 2006-10-31 03:47:28 UTC
Okay, some more data:
- I have replaced the broken USB hub, it still happens. 
- Like in bug 6374, my mobo is a VIA chipset. This is the EHCI controller:
0000:00:10.3 USB Controller: VIA Technologies, Inc. USB 2.0 (rev 82) (prog-if 20
[EHCI])

Now trying the patch from bug 6374.
Comment 9 Olaf Titz 2006-11-11 10:29:19 UTC
Still happens with the patch from 6374, but so far it has not happened without
any external hub connected.
Comment 10 Natalie Protasevich 2007-08-11 16:16:57 UTC
Any updates on this problem since?
Thanks.
