I have been trying to narrow this down as I find time.

A stock install of "OpenWrt 18.06.2, r7676-cddd7b4c77" works.

One thing different between my build and the stock build is that my
build seems to assign IRQ 0 to the wireless adapter whereas the stock
build assignes IRQ 41:

[Stock] # cat /proc/interrupts
           CPU0
  3:          0      MIPS   3  ehci_hcd:usb1
  4:        400      MIPS   4  eth1
  5:         51      MIPS   5  eth0
  7:     207161      MIPS   7  timer
 11:       8153      MISC   3  serial
 14:          0      MISC   6  ohci_hcd:usb2
 41:     148108  AR71XX PCI   1  ath9k
