Initial release ------------------------------------------------------------------------------- 2. KNOWN ISSUES No known issues. ------------------------------------------------------------------------------- 3. KNOWN PLATFORM ISSUES a. Enabling autosuspend: Autosuspend is supported by the Gobi3000 module and its drivers, but by default it is not enabled by the open source kernel. As such, the Gobi3000 module will not enter autosuspend unless the user specifically turns on autosuspend with the command: echo auto > /sys/bus/usb/devices/.../power/level b. Ksoftirq using 100% CPU: There is a known issue with the open source usbnet driver that can result in infinite software interrupts. The fix for this is to test (in the usbnet_bh() function) if the usb_device can submit URBs before attempting to submit the response URB buffers. c. NetworkManager does not recognize connection after resume: After resuming from sleep/hibernate, NetworkManager may not recognize new network connections by the Gobi device. This is a system issue not specific to the Gobi device, which may result in dhcp not being run and the default route not being updated. One way to fix this is to simply restart the NetworkManager service. -------------------------------------------------------------------------------
