Subject: [ath9k-devel] [3.3-rc2+] Thousands of ath9k warnings on dmesg before laptop froze
Date: Mon, 6 Feb 2012 00:29:07 +0000 [thread overview]
Message-ID: <20120206002907.GA1899@Pilar.site> (raw)
I'm testing the latest kernel 3.3.0-rc2+ I pulled from git
this morning.
My laptop just froze, and when I rebooted I noticed that /var/log/messages
contained 48 thousand (!) warnings coming from ath9k since a few hours
ago. I'm pasting the first one:

I must say that until the laptop froze, I didn't notice anything unusual
to the point of checking my dmesg. Sometimes the internet was slow,
but I thought it was unrelated to the kernel.
Is there any other info I should provide or the above warning is enough?
