nbd fixed this in https://dev.openwrt.org/changeset/28182 >> >> How to check if both are related, and related to the ag71xx driver >> mentionned in the kernel oops ("<ag71xx_poll+1dc/58c>") ? I posted some details in ticket: https://dev.openwrt.org/ticket/10071 I don't know to debug this further. I had no luck in trying to find out if I hit one of the BUG() in the ag71xx driver.
