Comment (by jacob):
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.:
root@OpenWrt:~# lspci -v
