I've got a device driver for MIL-1553b card called TA1-PCI, which could be found at https://github.com/qmor/elcus-1553-driver-linux Card is using PLX_PCI9030 PCI controller. Today i've found that this driver compiles, installes, but is not working as it should. Looks like it not receives any interrupts from PCI. I've test it again with kernel 4.2 and it works okay. What changes was made in PCI subsystem from 4.2 to 4.3 which could have impact this driver work.
