    rewrote the code via InterruptAttachEvent, everything worked
    
    The problem was that the functions printf and MsgDeliverEvent can not be used in the interrupt handler, I did not 
know that there are such limitations in QNX (I'll repeat once again, this is my first experience writing drivers for QNX
, I wrote mostly for Linux)
    
    formally did this - in the process of initialization a thread_irq is created, which registers an interrupt and waits
 for it, sends a signal
    
    void *thread_irq(void *arg)
    {	uint32_t ri, mi, mci, rci;
        int eu = 0;
        unsigned int minor = *(unsigned int *)arg;
    
        struct sigevent int_event; //текущее событие
    
        struct sigevent event;
        int i = 0,err = 0;
    
        printf("\nDEV_MIL_DRV_UDx: Start irq_thread(), minor = %d",minor);
    
    	//записываем номер MSI прерывания
    	device_mil[minor].irq_num = device_mil[minor].pci_info.Irq;
    	if(device_mil[minor].pci_info.msi)	printf("\nDEV_MIL_DRV_UDx: MSI enable, MSI irq is %d",device_mil[minor].irq_num)
;
    	else printf("\nDEV_MIL_DRV_UDx: !!! MSI DON'T ENABLE, YOU MUST DON'T USE INTERRUPT FOR WORK WITH MODULE!!!");
    
    	// создаем поток для драйвера(должны быть root права)
        if(ThreadCtl(_NTO_TCTL_IO, 0) != EOK){
            printf("\nDEV_MIL_DRV_UDx: You must be root!");
            pthread_exit((void*)-1);
        }
    
    	//регистрируем обработчик прерывания
    	int_event.sigev_notify = SIGEV_INTR;
    	device_mil[minor].di.int_id = InterruptAttachEvent(device_mil[minor].irq_num,&int_event,0);
    	if(device_mil[minor].di.int_id == -1)
    	{	printf("\nDEV_MIL_DRV_UDx: error interrupt attach");
    		perror("\nInterruptAttach:");
    		pthread_exit((void*)-1);
    	}
    
    	while(1){
    		//ожидаем прерывания
    		InterruptWait( 0, NULL);
    
    		printf("\nDEV_MIL_DRV_UDx: irq_handler(): begin.\n");
                    
                    !!!!!code!!!!
    
            }
    }
    
    now I will only use InterruptAttachEvent)))
    
    Once again many thanks for the help !!!)))
