Subject: Only one of two Intel Wireless 7260 PCI Cards are assigned a logical name (ubuntu 16.04 :: 4.7.0-040700-generic )
I believe I have an issue with the Intel wireless 7260 pci cards on my linux desktop
I have two wireless cards on a test PC I'm working on. And while I can see both cards, only the top card (in the physical location) is actually getting assigned the logical (interface) name.
This seems to be interment (though I've only had this computer running for two days) because there has been at least one occasion that I have seen both cards assigned an interface name at the same time (via ifconfig and NM). However, when I've had to restart the computer, the names are not always assigned for the 2nd (bottom) card -this is the case most of the time.
Attached is the dmesg for the case where I was able to get both cards to work (dm.txt) and the case where I am not able to get both cards to work (dmbad.txt)
I've switched out the cards (with other 7260 cards), move the cards to other locations, exchanged the locations of the cards, BUT only the top most device is ever assigned the an interface name.
I'm running: 4.7.0-040700-generic GNU/Linux Ubuntu 16.04.1 LTS
The two cards are the same Intel Corporation Wireless 7260:

Only one of the devices is getting assigned a logical name:

dmesg does not show that the 2nd device on bus 0000:02:00.0 has been detected by the wifi driver
{Attached as dmbad.txt}
and ifconfig only shows one device (obviously since lshw showed that only one was getting assigned a logical name)
