sys-net freezes when using 4G USB modem #2626

kravietz · Feb 10, 2017

Qubes OS version (e.g., `R3.2`):

R3.2

Affected TemplateVMs (e.g., `fedora-23`, if applicable):

fedora-23

Expected behavior:

Connect a Huawei 4G USB modem to sys-net through sys-usb and enjoy uninterrupted mobile networking.

Actual behavior:

Everything works, the 4G modem is detected by sys-net as Ethernet device, network is connected and everything works for around a minute and then sys-net becomes unresponsive.

Steps to reproduce the behavior:

Create sys-usb
Connect 4G USB modem to the laptop
qvm-usb displays
sys-usb:2-1 12d1:14dc:HUAWEI_MOBILE_HUAWEI_MOBILE
qvm-usb -a sys-net sys-usb:2-1
qvm-usb displays
sys-usb:2-1 12d1:14dc:HUAWEI_MOBILE_HUAWEI_MOBILE (attached to sys-net)
Shortly after a pop-up message is displayed from sys-net about establishing Ethernet connection. Internet connection works etc.
After around 30-60 seconds network connection to other VMs dies and sys-net becomes unresponsive. You cannon open a console in it or shut it down. Qvm-kill works however.

General notes:

Just for say I have the same problem with the builtin lenovo t450s 4g modem Le ven. 10 févr. 2017 13:25, Paweł Krawczyk <notifications@github.com> a écrit :

You can try to troubleshoot a frozen VM by accessing its console from dom0, for example using dmesg

To access the virtual machine console, use: sudo xl console vmname
login as root, and run dmesg

Check the kernel messages for sys-net and sys-usb

I have a similar issue where the USB Proxy fails on connect in sys-net. (If you want I can make a new issue for it.

Info about kernel version used for sys-net and sys-usb would be useful too. Is it the default 4.4.x?

Here's one kernel oops. I repeated the above scenario and this time it was sys-usb that froze with 50% CPU usage. Here's what appeared on the console when I tried qvm-usb -d on the device.

Here's one kernel oops. I repeated the above scenario and this time it was sys-usb that froze with 50% CPU usage. Here's what appeared on the console when I tried qvm-usb -d on the device.

And this is what happens on sys-usb after a minute or so after the modem was inserted:
