I've found some perhaps relevant bits of code here which force the
chip into and out of reset/sleep states.

It's possible that your BIOS doesn't fully reset the NIC upon startup.
It's also possible there are issues with the ath9k power save/resume
code. It's also possible they're all compounding to make things worse.
Are you able to completely and utterly disable any/all power saving on
ath9k, including APSM if you have it enabled?

Unfortunately the information I have is a bit sketchy. I'll do some
further digging (and hope I don't bug Atheros people too much :) to
see if I can extract out some more information about what's going on.

Thanks,


Adrian
