I have a EM9190 modem running in USB mode. The used driver is cdc_mbim. My current firmware is 03.09.03.00_ORANGE. It is working as expected, but after running for several hours, the firmware seemed to crash. dmesg returned the following:
cdc_mbim 4-3:1.0 wwan0: NETDEV WATCHDOG: CPU: 0: transmit queue 0 timed out 5132 ms
Any ideas on how to debug or fix this are much appreciated!
