I've followed the exroot tutorial to attach a usb pendrive to my openwrt router.
It seems to work well, but after some time (hours), when I try to access whatever configuration page via browser I get this string:
Status: 500 Internal Server Error Failed to execute cbi dispatcher target for entry '/admin/system/system'. The called action terminated with an exception: /usr/lib/lua/luci/template.lua:97: Failed to execute template 'cbi/header'.

This is the output of lsusb and dmesg
