We discovered that the built-in Toradex Wifi modules are having some problems when taking the interface down eg. ifconfig mlan0 down or terminating the wpa supplicant this sometimes leads to an unuseable wireless chip the chip is removed from linux (see the dmesg log below) and only available after rebooting. Also further calls to ask for network information with tool like ip link and ifconfig block forever after this event happend. Is there a fix or worakound available?
We are developing our firmware based on Toradex V3.0B2 and forked from this at an early stage when the development came online. I looked for commits related to this but didnt’t have the feeling this is already solved by some commit we missed.
