I can also confirm that the Kernel posted in #20 resolves the issue with
my Emulex Zephyr-X FC adapter.

Some SVG-icons in the toolbar aren't displayed if libqt4-svg is not

It's looking good so far, I couldn't reproduce the issue with Alan's

As this issue was very annoying, I bought a headset-adapter and switched
away from using a USB audio device to using the built-in audio adapter
of my Thinkpad X121e, so this issue was off my radar. Sorry for the lack
of feedback. I've just given the latest kernel a test and it still
happens, which
I gave it a short try last week, but failed. After taking a look at the default
Ubuntu kernel configuration I found out why:
# CONFIG_IRQSOFF_TRACER is not set
Since I'm currently on vacation and don't have the hardware with me,
I'll give it a try next week with the irqsoff-tracer enabled.

Okay, it seems to work this time. See the attached file for the klog

@stern: Since the latency was changed back to 1ms the bug has become
quite rare for me (one or twice in 12 hours of using the audio device),
so the usbmon file will get quite big. Maybe it happens more often for
someone of the other users affected. Also, what happens is that when the

Yes, it just happened again with the kernel from #4:
Linux sleeper 3.8.0-25-generic #37~lp1191603v1 SMP Mon Jun 17 18:19:17
UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

[46066.222047] cannot submit urb (err = -18)
[46066.222055] cannot submit urb (err = -18
I've seen the issue appear again with 3.8.0-26.38 now as well, but it happens
much less often. Commit 6a41b4d added a new codepath that returns -EXDEV
(which is -18), which seems to get triggered sometimes...
So I still consider this a kernel bug and we should let the guys at the lkml
know.
Se
Yes, that kernel solves the issue. I tested recording and playback from
an USB audio adapter for 7 hours, and the problem did not appear. It
didn't last that long before the fix.
