[Bug 1593835] Re: Transient panic on boot with wily proposed kernel (4.2.0-39)

[Mike Gerow]

I haven't seen this happen in a while and I'm beginning to think more
and more it actually had something to do with my system and not the
kernel. Moving to invalid.

[Bug 1393931] Re: Cannot connect to Android-Device using USB 3.0 and mtp protocol

[Mike Gerow]

This also affects trusty and makes it impossible for some users to
transfer files over usb on newer phones. Just patching in the upstream
commit that apparently fixes this
(4a9e6046319ad834b924031d74f50e58b88d7d84) seems to work fine. It
applies cleanly, builds cleanly, and appears to work. If I provide a
debdiff for that is that the kind of thing we could bring to trusty-
updates?

[Bug 1557172] Re: khubd/usbhid deadlock(?) creates processes in state D

[Mike Gerow]

Checking in again, no real changes in my observations of this bug. It's
worth noting that this only occurs in 0.5% of our machines (yes, half a
percent!). A good chunk of them are servers with DRACs, but there's a
nontrivial amount of desktops that hit this issue too.

I'm having affected users try running the linux-generic-lts-xenial
kernel to see if that makes the issue go away. Will update this bug with
my findings.

Of course. The device itself doesn't have any interesting markings, but
luckily I still have the packaging it came in too.

Not checking that this is a security vuln because trusty-backports
technically doesn't get security attention.

[Bug 1593835] Re: Transient panic on boot with wily proposed kernel (4.2.0-39)

[Mike Gerow]

Sadly no, I only saw it happen once and I have no idea what might have
caused it. The one and only time I saw it was with the 4.2 kernel,
though.

I don't have access to the machine that it happened on anymore,
unfortunately, but I'll see if I can reproduce the issue on another
machine I have access to.

[Mike Gerow]

If it's any help at all: my personal laptop running Debian unstable
doesn't seem to have the same issue with this device (it's on 4.5.0).

Also, this adapter specifically is the "Monoprice USB3.0 Gigabit
Ethernet Adapter" , which
is Realtek 8153-based as the bug title mentions.

[Mike Gerow]

And by "doesn't seem to have the same issue" I mean I still get the
"Stop submitting intr, status -71" error when disconnecting the device,
but it doesn't seem to randomly stop working between when I initially
plug it in and some time in the future (probably averages around 15
minutes).

UTC 2016

I also get a similar message about 'Failed to disable LTM' if I just
unplug the device before the breakage occurs.

I've attached lsusb before the breakage occurs (so you can see the
device) from the mainline kernel.

Interestingly it appears the drivers on trusty and wily/mainline are
different (r815x vs r8152) yet still exhibit similar troubles. I'm still
digging around to try and figure out why this doesn't seem to be
working, but I was wondering if you all had any idea what might be going
pear-shaped here.

Thanks!

[Bug 1557172] Re: khubd/usbhid deadlock(?) creates processes in state D

[Mike Gerow]

Sorry, I'm not super familiar with apport (our security folks make us
disable it because they get upset for reasons I don't quite grasp).

I tried to install apport and python-apport, but no dice on actually
running apport-collect.

$ apport-collect 1557172
Traceback (most recent call last):
  File "/usr/bin/apport-cli", line 370, in

Is there some other way for me to get the info you need?

[Bug 1557172] [NEW] khubd/usbhid deadlock(?) creates processes in state D

[Mike Gerow]

Public bug reported:

(Note that the attached logs are not a machine exhibiting the issue)

I've observed this issue specifically on Dell's PowerEdge R410 with its
DRAC. I manage quite a few other machines with DRACs and haven't seen
this issue so it may be limited to the R410. I've seen cases of this
both with the precise and trusty kernel.

Basically, what happens is that things that read any info about the
DRAC's usbhid device will block in an uninterruptible state. A quick way
to do this is with "cat
/sys/devices/pci:00/:00:1d.0/usb5/5-2/manufacturer". This means
that commands like lspci will block as well. The thing is that it
doesn't happen every time, but once it happens the first time all future
reads on the device will block in state D too.

This is also associated with the following from the kernel (first from a 
precise machine):

[Bug 1104230] Re: DisplayPort 1.2 MST support is missing in the Intel driver

[Mike Gerow]

Hi Dariusz,

I tried your changes and don't seem to be able to see the my other
monitors any more. I'm curious if this has something to do with the dock
I'm using to connect my laptop to my displays, though, because the
external mouse and keyboard I have hooked up to the dock don't seem to
be working either.

Let me know if there's anything useful I can do to help you. I'm trying
this on a test machine so it's not a big deal if things end up breaking.
