rpi/dwc2 kernel panics

Hi guys,
I just tried today's Linus' master (45f7fdc2ff) with usb-linus (3635c7e2d5)
merged on top to give the latest dwc2 fixes another try.
Unfortunately I'm getting various crashes on system startup. Kernel boots
fine, dwc2 and the integrated smsc95xx are detected, but somewhere in the
init sequence the system panics.
Hard to say when exactly, but it looks like it's happening upon setting
up the usb ethernet adapter (with dhcp in my case).
It doesn't crash on every boot, maybe 3 in 10 times. And it doesn't seem to
crash when booting with "nousb", at least not so far.
Do the traces below ring any bell?
Thanks,
Andre
