Vista NDIS Miniport Enable/Disable Problems

Hi!

Has anyone else seen this?

We have an NDIS Native 802.11 miniport driver for Vista on both 32- and
64-bit platforms. On 64-bit, we see a large delay during miniport
initialization following subsequent enable/disable/re-enable passes, so that
each miniport initialization takes longer than the previous one. At some
point, the OS seems to freeze or response very slowly (e.g., the cursor
takes forever to move following a mouse movement). We don't see this on
32-bit.

Does anybody have an idea what could be causing this?

Thanks!

Is your miniport's halt handler getting called? Unloaded?

After loading ndiskd, what does !miniport <miniport address> report? (you
can get the address by listing all miniports via !miniports). Turn on
Driver Verifier for your driver. How long is a long delay? Five seconds?
Five minutes?
