in my case it's probably more my fault, since it happens in a driver-module
that im writing - though i'm begining to think otherwise. Adding
debug printfs fixes the panics, which most probably means some
timing problem. The code is experimental, but if someone would like to
take a look, i've placed it, together with the panic in:
