| |
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?
