Okay. I've sent logs (dmesg and lspci) from both 4.2 and 4.3 to bugzilla

Hello. 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.
Thank you very much for this problem report. There were many PCI
changes between v4.2 and v4.3, and without more information, I can't
guess what might be causing this problem.

I opened a bug report at https://bugzilla.kernel.org/show_bug.cgi?id=111211

Please attach complete dmesg logs for both v4.2 and v4.3 to that bug
report. Also, please attach the complete "lspci -vv" output (as
root).

Thanks!
