[Bug 1556471] Re: Connecting an Osprey 2 Mini (USB cellular wireless router) sometimes causes an endless reset loop or a kernel panic
Cut from Description.
** Attachment added: "syslog"
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1556471/+attachment/4598145/+files/syslog
** Description changed:
Steps to reproduce (happens > 50% of the time, but not every time):
- Turn on an Osprey 2 Mini
-
- Connect it to a USB port via a USB cable while both the device and
- computer are on (i.e. hotplug)
+ Turn on an Osprey 2 Mini, and connect it to a USB port via a USB cable
+ while both the device and computer are on (i.e. hotplug).
Observed symptoms:
- - sometimes the Osprey 2 Mini goes into an endless reset loop (visible as the LEDs on the front of the device flashing rapidly), being reset approximately every 200ms; on such occasions, the Ubuntu user interface often reacts as though I'd inserted an audio CD containing corrupted data (e.g. via repeteadly adding an "Audio CD" icon to the launcher and then removing it, and putting up dialog boxes complaining about failure to read the data)
- - sometimes the kernel panics (often some time after the reset loop starts, perhaps up to 10 seconds); when this happens there was always or nearly always a reset loop occurring beforehand
- - sometimes the device resets once or not at all, then works as expected (showing up as a network interface, and allowing me to communicate to the Internet with a wired connection); I'm currently using an Osprey 2 Mini for this purpose right now

- I haven't been able to gain much information about the source of the
- kernel panics, as they lock up the entire system (forcing a hard power
- off). Alt-Sysrq commands don't work in this state (even though I have
- them enabled), and sometimes the Caps Lock light flashes repeatedly,
- both signs of a panic. The logs end some time before the panic occurs;
- presumably the panic means that the log file is never written to disk.

The reset loops also occurred when I was using Ubuntu vivid. The kernel
- panics (which identify Linux as the broken package, as no user action
- should cause it to panic) only happened after an upgrade to wily.

- I couldn't get ubuntu-bug to work (after gathering information, nothing

Title:
Connecting an Osprey 2 Mini (USB cellular wireless router) sometimes
causes an endless reset loop or a kernel panic
Status in linux package in Ubuntu:
Incomplete
Bug description:
Steps to reproduce (happens > 50% of the time, but not every time):
Turn on an Osprey 2 Mini, and connect it to a USB port via a USB cable
while both the device and computer are on (i.e. hotplug).
Observed symptoms:
- sometimes the Osprey 2 Mini goes into an endless reset loop (visible as the LEDs on the front of the device flashing rapidly), being reset approximately every 200ms; on such occasions, the Ubuntu user interface often reacts as though I'd inserted an audio CD containing corrupted data (e.g. via repeatedly adding an "Audio CD" icon to the launcher and then removing it, and putting up dialog boxes complaining about failure to read the data).
- sometimes the kernel panics (often some time after the reset loop starts, perhaps up to 10 seconds); when this happens there was always or nearly always a reset loop occurring beforehand.
- sometimes the device resets once or not at all, then works as expected (showing up as a network interface, and allowing me to communicate to the Internet with a wired connection); I'm currently using an Osprey 2 Mini for this purpose right now.
The kernel panics lock up the entire system (forcing a hard power
off). lt-Sysrq commands don't work in this state (even though I have
them enabled), and sometimes the Caps Lock light flashes repeatedly.
The logs end some time before the panic occurs.
/var/log/syslog:

The reset loops also occurred when I was using Ubuntu vivid. The
kernel panics only happened after an upgrade to wily. Output of lsusb
-v is attached.
