try to unload driver on smp-somputer and system gets bsod (in ExFreeMemoryWithTag), on uni-processor computer evererything is ok.

Probably syncronization problem…

Memory was already released or your memory pointer was corrupted. Put the breakpoint on the pointer access and trace all operations with it during your driver unload.
