Option 225 3G USB Stick removal causes system lock

[Alan Lord]

Fully updated Ubuntu Karmic as of today (25/08/09 at 10:05 BST).

Hardware: Asus 1008HA

3G dongle: Option ICON 225 (Uses kernel module hso.ko)

Plugging in the USB stick and removing it without attempting to make a connection does not cause the failure.

To cause failure, plug in the USB device, attempt to make a connection in NM (it doesn't matter if the connection succeeds or not) then disconnect using the NM interface. OK so far.

Upon removing the dongle, the entire system locks up.

FYI, these symptoms used to happen with the early versions of the hso module prior to being included in the mainstream kernel tree in 2.6.27 IIRC. I tested this with all available Karmic kernels on my system: 2.6.31.3-generic, 2.6.31.4-generic, 2.6.31.5-generic, 2.6.31.6-generic, 2.6.31.7-generic, and the problem is the same. However, I am *pretty sure* this did not used to happen a couple of weeks ago. Not much help I know.

It is repeatable *every-time*. No mouse movement is possible, no keyboard commands are accepted apart from doing Alt+SysRq REISUB will cause a reboot.

I had an ssh connection into the device and was tailing /var/log/messages. No output upon removal and the ssh connection is also broken.

I just reproduced this issue. Fully updated Karmic box, connected OK to Orange, removed the dongle and it locked up. Was OK a little while ago on Karmic

[Luke Faraone (lfaraone)]

Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately, we can't fix it without more information.

Please run the following command which will attach necessary information:

apport-collect BUGNUMBER
if you are using Karmic Koala (9.10) or newer, or

apport-collect -p linux-image-`uname -r` BUGNUMBER
if you are using Jaunty Jackalope (9.04)

Bear in mind that you may need to install the python-launchpadlib package from the universe repository with 'sudo apt-get install python-launchpadlib'. Additionally, when prompted to give apport-collect permissions for Launchpad you will need to give it at least the ability to "Change Non-Private" data as it will be adding information to your bug report.

If you are using an older release or cannot use apport please at least add the following information (pay attention to lspci's additional options):
First run the following commands:
1) uname -a > uname-a.log
2) dmesg > dmesg.log
3) sudo lspci -vvnn > lspci-vvnn.log
4) cat /proc/version_signature > version.log
then attach the files separately to the bug report (not pasted into comments or tar/zip-ed).

For your reference, the full description of procedures for kernel-related bug reports is available at https://wiki.ubuntu.com/KernelTeam/KernelTeamBugPolicies. Thanks in advance!

This affects me too on karmic, with Option UMTS USB/PCMCIA Card.

[Luke Faraone (lfaraone)]

Hi,

Can you also confirm that this bug occurs in the mainline (unmodified upstream) kernel? See https://wiki.ubuntu.com/KernelTeam/MainlineBuilds for more information on how to test this out. If this issue still occurs on that kernel, then it is also an upstream bug.

[Hein Gustavsen (hein-gustavsen)]

I can confirm that the same happens with mainline kernel 2.6.31-02063103. System froze completely. I could not get the kernel messages.

[Hein Gustavsen (hein-gustavsen)]

This works better with the new kernel 2.6.31-14-generic. The system does not hang when the device is removed while disconnected, but when the devices is removed while connected to the Internet, the system hangs like before.

[Eric Miao (eric.y.miao)]

Hein,

Could you please attach the error message (dmesg) when the system hangs
while connected to the Internet? Is it the same symptom and same message?

[Hein Gustavsen (hein-gustavsen)]

Sorry, but I haven't been able to get the error message as the system now freezes completely after device removal. It is the same symtom, but I managed to get the error message one time before.

[Saulius Sinkunas (ssinkunas)]

I guess the problem is with the HSO module. It doesn't unload itself fully - device /dev/ttyHS1 remains in the system (although other /dev/ttyHS* are removed). Maybe that's why everything locks up. There is a new HSO version 1.12 but it doesn't compile on 2.6.31 because of changed structures.

BTW only Network Manager locks up the system. Using HSO Connect to connect to the Internet doesn't cause such failure - it becomes impossible to connect to the Internet but at least it doesn't lock up the system.

[Kai Ritterbusch (kai-ritterbusch)]

hello!

I have to reconfigure nm every time i want to use the option icon 225 dongle. dmesg says modem-manager segfaults. if i can help you, please tell me what to do.

[Jeremy Foshee (jeremyfoshee)]

This bug report was marked as Triaged a while ago but has not had any updated comments for quite some time. Please let us know if this issue remains in the current Ubuntu release, http://www.ubuntu.com/getubuntu/download . If the issue remains, click on the current status under the Status column and change the status back to "New". Thanks.

[This is an automated message. Apologies if it has reached you inappropriately; please just reply to this message indicating so.]

[Alan Lord (theopensourcerer)]

Well, I used the 225 yesterday on my netbook with Lucid, yanked the dongle out and the system worked as I'd expect, e.g. I got a notification that my network connection had been disconnected and everything else continued to operate.

So I guess this now resolved.
