Thanks for your advice!
I've posted a bug report upstream:
http://permalink.gmane.org/gmane.linux.usb.general/129790
I also checked out some older kernels.
The problem is present since 3.18, while 3.17.x was OK.
Or rather, had other, less dramatic problems on the machine.

Steps to reproduce:
- open a terminal

In a virtual terminal, the command prints the name of the first device
it finds, then the system freezes completely. In a terminal of the
desktop, I don't even get the name of the device, the

I've verified that the freeze on shutdown is caused by the same commit.
Contrary to my initial report here, the freeze on shutdown happens late in the
sequence, not early.
I'm used to much longer shutdown times from my desktop :-)

Valentine, your problem is almost certainly not related to the one I reported
here.
You should seek advice in forums or on mailing lists for your computer and/or
distribution.

As suggested on the linux.usb mailing list, I've added some additional debug
print statements to the first bad kernel. They are not triggered by "lsusb -v"
though. I'm attaching kernel debug output from the boot sequence of two kernels:

For the records, here's a screenshot (photo) of the system after a freeze.
Series of actions to get there:
1. enable kernel debug output
2. detach external mouse, to verify that messages appear
3. hit enter to get a new prompt line
4. trigger the freeze with "lsusb -v"
lsusb prints the name of
The previous log for the "bad" kernel was incomplete, due to kernel
buffer overflows caused by systemd output. I've switched that off as
explained here: https://bugs.freedesktop.org/show_bug.cgi?id=76935#c1

As suggested by Alan Stone on the linux-usb mailing list, I've verified
that the "USB cable is bad" messages are caused by the order in which
the USB devices are initialized.
I've also found a new way of triggering the freeze on a bad kernel:

I removed the bios-outdated tag. The guy who wrote about his BIOS update
in comment #9 has a completely different problem and commented off-
topic.

Current state of things: I've tracked down the code line where the
freeze happens. It's in function ehci_halt within file ehci-hcd.c. The
function is executed on shutdown as well as when the usb devices on the
bus are about to be probed again. The latter is triggered by "lsusb -v"
as root.
Installing Xubuntu 15.04 to boot in UEFI non-secure mode has some
challenges of it's own. But once I got the system working, it doesn't
freeze anymore.
If you want to use legacy BIOS mode, you'll have to compile a kernel.
However, it is not necessary to apply the patch above. Just disable the

The cause of the freeze seems to be a BIOS problem, as Alan suggested on
the linux-usb mailing list. When booting in UEFI mode (from a Xubuntu
15.04 installation medium), three of the devices listed by lspci are
missing, compared to legacy BIOS mode. One of those is the device that
caused the

I got a replacement board and the error seems to have gone. I did run
iperf for over an hour and no hanging was detected. Looks like the board
was faulty, leading to the exact same behaviour as described in the

igb: Detected TX unit hang

When putting network load onto the Intel I210 network card using iperf,
i can reproducible get the igb driver to hang after 10-60 seconds. This
regression was also discovered on 3.16er kernels (see #LP: 1492146) -
and it's still existing on newer kernels as well. This is on
I just tried to boot with the following packages installed:
linux-headers-4.7.0-040700rc7_4.7.0-040700rc7.201607110032_all.deb
linux-headers-4.7.0-040700rc7-generic_4.7.0-040700rc7.201607110032_amd64.deb

First boot hung
I just tried booting with pcie_aspm=off. It took 7 seconds until freeze
after starting iperf. The funny thing is, that i'm using the igb-driver
on the other side of the test, but on an I354 controller.

The "no longer affects" is not correct, but the assignment to the
correct source package was wrong.

Hi, i'm encountering the same/similar bug on xenial 4.4.0-28-generic. If
i apply network load via iperf i get the unit (Intel 210i) reproducible
to hang. Maybe this is a regression or another bug. The network
interface does not recover, i have to reboot the machine to get it back
online. dmesg
I am using the C2550. I just tried the "disable intel speedstep and
C-state" hint but within 60 seconds i got the tx unit hang again.
