Subject: [igb] AER timeout - resend.

Sending this to both netdev and kernel since i don't know if it's the
driver or the pcie AER that does something odd - the machine was
stable before 3.19 and PCIE AER.

Everything started out like i first sent to linux nics () intel:
------

And today i had some issues and wondered why things was broken, i was met with:

So two out of two disks just failed and isn't replying anymore?

Seven hours after a AER this machine who's intel ssd:s are idle just
fail to respond? ;)

Anyway, will reboot it when i get home - any idea/suggestion is more
than welcome.
