Try it again after you reboot. I think long delay when you do ifconfig up
occurs when the driver is trying to allocate chunks of shared memory with
NdisMAllocateSharedMemory(). It wants a lot of little buffers, and it
takes a while to allocate them all through busdma. Also, if the system
has been running for a while and memory has become sufficiently fragmented,
the allocations can fail. Unfortunately, NDIS drivers to not allocate
shared memory buffers once at attach time: they allocated them every
time you do MiniportInitialize() (and release them when you do
MiniportHalt()).
