Incarca memory.dmp in WinDbg si da !analyze -v, o sa-ti zica exact ce
linie genereaza BSOD-ul; cel mai probabil apare in IRQ handler pe
ramura care trateaza intreruperea THREI, pentru ca activarea ei duce
la BSOD. In principiu ai incercat sa accesezi o zona de memorie
swapabila sau o adresa invalida din context intrerupere.

Asigura-te ca zonele de memorie alocate pe care le folosesti in
handelerul de intrerupere sunt alocate din NonPagedPool.
