Disappearing WiFi card

I have an Arch-based server (Zotac Nano, AMD Kabini-based) which doubles as WiFi access point using a miniPCI Atheros WiFi card.

If I start it form cold boot (as in “it was off”), then everything starts and works fine 100% of the time. However, if I then run “reboot” command, then there is 80% chance that then the system is back online, the WiFi card will be gone.

Here is dmesg after cold boot:

and dmesg after reboot:

Here is lspci after cold boot, which is the same after reboot:

So at least the card is still physically visible.

What other logs can I provide?

I had this problem since a year now. With every kernel update there was over this period. It is a remote server, so being able to manually turn it in after a shutdown is rarely possible.
