User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:10.0) Gecko/20100101 Firefox/10.0 I am running openSUSE 12.1 x86-64 with kernel 3.1.0-1.2-desktop on an Acer Aspire 1810TZ (Genuine Intel(R) CPU U4100 @ 1.30GHz) and I use a MedionMobile Web Stick S4011 for internet connection (it is actually an Huawei E160; idVendor=12d1, idProduct=1003). I manage the web stick using a Java program provided by the 3 operator on the Huawei E220 web stick; I do not think this is the culprit since it is more than one year that I use it without problems and with oS 11.4 I had no problems as with oS 12.1. I obtain a kernel panic with a completely frozen system (even magic sysrq does not work; I have to push the power button for 5 seconds in order to power off the laptop) when I unplug the stick after I close the connection. However this happens only if I do not wait enough time (about 5 seconds) after the end of the connection. /var/log/messages does not report the panic and I have not found any useful information in the logs; so the only thing I can attach is a picture of the screen (I reduced the size of the picture to 1024x768; if you need, I can also provide the full resolution picture - 3264x2448). If you need more information, you have to tell me how I can obtain them. Reproducible: Sometimes Steps to Reproduce: 1. Start an internet connection using the web stick 2. Close the connection 3. Unplug the webstick in a short time Actual Results: Kernel panic. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
