I'm trying to connect a stack of Raspberry Pi Zero's (50) through a network switch. I'm using an USB ethernet adapter (10/100 Mbit Realtek 8152 based). Most Zero's appear to function fine everytime, but some Pis randomly don't start up well. I don't think it's a power problem, there is sufficient supply with good cabling. I have also not measured voltage drops.
I checked dmesg while it started up well, and I also logged dmesg when the startup was not successful (and the Pi didn't come online). I will post both logs. The problem seems to be:
