There aren’t many ath9k log messages.  Here are the messages from

lspci says this about my network controller:

02:00.0 Network controller: Qualcomm Atheros AR9285 Wireless Network Adapter (PCI-Express) (rev 01)

It used to work fine for several months.  Not sure if it’s failing or if
there’s bad interaction with the kernel/libreboot.
