Maybe something is wrong in DMA-related code in your driver?

Hi!
I've found that KsPinGetLeadingEdgeStreamPointer always returns NULL
while the driver is running under Server 2003 SP2 with PAE enabled on
computer with more than 4GB RAM. The capture board implements BusMaster
S/G DMA with maximum transfer size approx. 486K. The debug version of
ks.sys doesn't print out any kind of warnings. If I disable the PAE
support through boot.ini /execute option the problem disappears. May be
someone has any information about this issue.
Thanks
.
