If the problem exists with the original Linux driver as well (which one
is it precisely?), you may discuss this on the Linux kernel mailing list
or (if it exists) on the related subsystem list first (see
linux/MAINTAINERS for who's behind that driver and where to post to).

Anyway, also worth a try is to check the card in some different PC.
Maybe it's the combination what causes troubles here.
