netsc520 - skeleton in the closet ?

netsc520 - skeleton in the closet ?

[devzero]

i'm doing some module testing from time to time and i'm somewhat sure, that there is an issue with netsc520 module, as i have seen more than one occasion that after load/unloading of that module (w/o presence of the appropriate hw), other modules had issues.

see http://marc.info/?l=linux-kernel&m=120664963508105&w=2 for example.

now,by chance i came across this one: http://marc.info/?l=linux-kernel&m=118274309325836&w=2

so, it sounds there is a known issue with netsc520, but i'm not sure if it's the related and if that mentioned patch has been posted, at least i don't find it in git due to x86/64 unification.

maybe someone has a clue.... ?
