timer vs thread

NTDEV
1

Hi,
I noticed this strange behaviour in my Ndis Miniport driver, which I dont
know why.

If I execute NdisMEthIndicatereceive() from a periodic timer expiry
routine, it works fine; however if I execute the same from a system thread
loop (created by PsCreateSystemThread), it gives me following error in
SoftIce :

“Assertion failed : MINIPORT_LOCK_ACQUIRED((PNDIS_MINIPORT_BLOCK)(…)”

What could be happening?

Thanks in advance.
Raj

NdisMEthIndicateReceive must be executed at DISPATCH_LEVEL (if your miniport
is a serialized one). System threads I think don’t execute at that level.
