 am si eu urmatoarea problema: activez intreruperea pentru Com1 si la intrarea in ISR imi da eroare cand incerc sa accesez campuri din structura device-ului definita de mine. Astfel, sectiunea de cod din ISR este:

BOOLEAN Isr(PKINTERRUPT pInterrupt, PVOID ServiceContext) {
    PDEVICE_OBJECT device = (PDEVICE_OBJECT)ServiceContext;
    struct uart16550_dev *dev=(struct uart16550_dev*)device->DeviceExtension;
    ULONG PORT = dev->COM;     ==> AICI SE GENEREAZA BLUE SCREEN
    ....
}

     Sorry pentru post, am rezolvat problema cand m-am uitat mai atent semnificatia parametrilor.
Pentru cei care mai au asa ceva, folositi astfel:

BOOLEAN Isr(PKINTERRUPT pInterrupt, PVOID ServiceContext) {
    PDEVICE_OBJECT device = (PDEVICE_OBJECT)ServiceContext;
    struct uart16550_dev *dev=(struct uart16550_dev*)ServiceContext;
    ULONG PORT = dev->COM;
    ....
}
