Try this patch ... I have that card and noticed it requests 256 bytes and
the MEMUNIT is 4096 if I recall correctly so the math returns 0 for
"size/MEMUNIT" which is not good. To me this seems like the code should
round up fractions, but for now I just bump up the size if the request is
less then MEMUNIT. Hopefully someone that knows what is to happen can
fix it. If you verify that this fixes your problem I will send-pr it.
Also note in -current the sio driver is broken for pccard. I have a gross
hack that didn't work for someone else but worked for me on a -current
of a month ago. Unfortunately I can't test with a more update -current
right now.
