Hi Arty,
I have the very same problem as Gge (though the error shows up immediately after the "Domaininit done" event.) I tried your tcpip patch, but I still get the error.
Gge: hmm i'm not sure. I wonder if any big guns in DPCs will help out here. Please try this patch. My feeling is that TransferDataComplete is being allowed to run parallel with the work item. The only way i can see this happening is if somehow a buffer is reclaimed before its fully freed. This does seem to be the same bug as before but i'm not convinced its a regression so much as the same bug having been recently hidden and then reexposed. I've also ordered an RTL8139 card for the real hardware box i intend to start using for reactos. No time like the present to try this myself.
