http://bugzilla.novell.com/show_bug.cgi?id=496401 Summary: The hso driver for 3G mobile nework devices causes kernel crashes Classification: openSUSE Product: openSUSE 11.1 Version: Final Platform: All OS/Version: openSUSE 11.1 Status: NEW Severity: Critical Priority: P5 - None Component: Kernel AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: nice@titanic.nyme.hu QAContact: qa@suse.de Found By: --- User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; hu-HU; rv:1.9.0.8) Gecko/2009032600 SUSE/3.0.8-1.1.1 Firefox/3.0.8 The hso driver (/lib/modles/VERSION/kernel/drivers/net/usb/hso.ko) sometimes causes very difficult situations, for example when the connection gets lost somehow, and then I unplug the device, and want to restart the frozen NetworkManager, then either it's impossible to shut down the modem_manager (consumpting a constant 100% CPU load) and unload the hso module, or a kernel crash occurs when I attempt to do so. In the last few days, several times a day, either I had to totally restart my system, or I suffered a system crash. However, I recognized, that there is a new version of the hso driver (1.9) which seems to eliminate the mentioned kernel instability problems. The driver can be downloaded from http://www.pharscape.org/hso.html , and can be built by a simple make ; make install cycle, without modifying the kernel source. The new module will be placed as /lib/modles/VERSION/kernel/drivers/net/wwan/hso.ko , so it does not replace physically the current 1.2 hso driver. However, I hope that you can find a way to include this driver in the kernel srpm (and thus in the final rpm) package, and you can release it with the next kernel update. Reproducible: Sometimes Steps to Reproduce: 1. Connect with a hso driven 3G modem 2. Wait until the connection gets somehow lost 3. Unplug the device 4. Stop the network subsystem 5. Try to unload the hso module and kill the frozen modem_manager process Actual Results: Either the system crashes or you have to restart it in order to use it again. Expected Results: You should be able to normalize the situation without a reboot or system crash. (In an ideal world you wouldn't even have to fiddle with commandline to repair your 3G connection :) -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
