Subject: [ath9k-devel] Warning in ath_rc_get_highest_rix()
Date: Wed, 4 Jan 2012 17:46:45 -0500 [thread overview]
Message-ID: <20120104174645.259c3166@mj> (raw)
Hello!
I hit this bug on a freshly installed Fedora 16 and judging by the
duplicate bugs it looks like many Fedora users are hitting it too:
https://bugzilla.redhat.com/show_bug.cgi?id=771113
The standard Fedora kernel uses Linux 3.1.6 with
compat-wireless-3.2-rc6-3, but I was able to reproduce the same warning
with the bleeding edge compat-wireless for December 31, 2011.
The warning only happens with one wireless router. I'm not sure I can
reproduce it on purpose, but my abrt was showing about one hundred of
instances of that warning in a few hours.
Other bug reporters report that the warning appears after their laptop
was woken up from sleep. That my explain why I have never seen that
warning with self-compiled kernels from wireless-testing.git, as I
normally don't enable many power management features.
I'm going to "see" that router once in a while, so if anyone has an
idea what patch to try, I can do it.
The code that triggers the warning is in ath_rc_get_highest_rix()
(drivers/net/wireless/ath/ath9k/rc.c), and it reads:
/* This should not happen */
WARN_ON(1);
