I'm not sure if this is helpful to you or not, but since I'm having this problem as well I thought I may as well add a few comments regarding what I found:

  • Uninstalling the driver ('opkg remove kmod-ath10k') causes the error message to disappear (not a solution but suggests that the problem is indeed related to the driver)
  • If the driver is installed, running 'lspci' causes a seg fault on first attempt then crash on second ('opkg install pciutils') otherwise it works, e.g.:

Upgrading to "bleeding edge" (r47811) resolved the problem (tested on TP-LINK Archer C7 AC1750 v1.0).
