Re: [win-pv-devel] xenvif Win7 BSOD - DRIVER_POWER_STATE_FAILURE

[Martin Cerveny <martin@xxxxxxxxx>]

Hello.

I think I found it:

When IN_NDIS_MAX is hit (NDIS_RECEIVE_FLAGS_RESOURCES) and more then one packet 
in NetBufferList,
you increment Indicated more then one, send through 
__IndicateReceiveNetBufferLists(),
but there is side effect that split linked list, __ReceiverReturnNetBufferLists() free only the first one and increment 
Returned only by one.
Some testing patch added but rethink patch by your own.
