https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=201117 --- Comment #1 from commit-hook@freebsd.org --- A commit references this bug: Author: adrian Date: Sat Jul 4 02:59:31 UTC 2015 New revision: 285120 URL: https://svnweb.freebsd.org/changeset/base/285120 Log: Wake up the hardware before doing anything in sysctl. This stops the panics that occur on MIPS platforms when doing say, 'sysctl dev.ath.0' whilst the MAC is asleep. The MIPS platform is rather unforgiving in getting power-save register access wrong and you will get all kinds of odd failures if you don't have things woken up at the right times. Tested: * QCA9558 (TP-Link Archer C7 v2) * AR9331 (Carambola 2) .. with no VAPs configured and ath0 down (thus the MAC is definitely asleep.) PR: kern/201117 Changes: head/sys/dev/ath/if_ath_sysctl.c -- You are receiving this mail because: You are the assignee for the bug.
