Hello, i hope this is the right way to report an problem with the "option" driver. I have got an small laptop Acer Timeline 1810TZ with an included Huawei Modem EM770W. It is registered in the usb-subsystem with the following entry: 002 Device 004: ID 12d1:1404 Huawei Technologies Co., Ltd. The device is most of time working, but often it leads the modem software like UMTSMON or knetworkmanager to hang an do not the right things. I get a lot of kernel error logs from the "option" driver if i use this device: [ 7728.715228] option: option_instat_callback: error -2 And the very ugly think is, when i use the device it can cause the whole system to crash. First my display is going black and after 3-5 seconds later the Laptop is turned off, or is doing a hard reset. This happens sometimes after some minutes or after some hours working in 3G mode. I tested this with Kernel 2.6.31, 2.6.32 and now with 2.6.33rc3. Same behaviour. It also not distribution specific, tested with openSuSE and Ubuntu 9.10. No kernel errors are reported during/after the system reset. I do not know if this behaviour has to do with the "option" driver, but it only happens if i use the 3G modem. I have send the Laptop to Acer to check for an hardware related problem, but they doesn't have found anything. The preinstalled operating system Windows 7 runs a whole day in 3G mode without any problems, so it doesn't seems to be an hardware failure. Thanks for your help.
