Kernel Panic when using g_ether
Closed this issue · 0 comments

I was just playing around with some TXTs in a daisy chain via USB and this problem is occurring all over after a few minutes of work...
Situation:
Connect one TXT via its USB2 port to another TXT´s USB1 port. The first TXT will crash like this after a few minutes.
Maybe someone has an idea to fix it.
