I've been fiddling around with the cooling on my Radeon 4890 and replaced it
with an Arctic Cooling I had mounted on my old 4850 card.
It worked for a while, but then the screens went black and the fan maxed out
completely. BUT I noticed that the computer was still running, so it hadn't
crashed. I could SSH in and reboot it manually.
I figured the card had gotten to hot, so I switched the coolers again. But the
problem was still there! I started monitoring the temperatures, and they really
weren't any hotter than normal. Around 45 degrees C. The weird behavior still
repeated itself, even when just browsing the web for a couple of minutes. One
time it happened after only 2-3 minutes!
I then booted into Windows to see if the problem was there, and nothing
happened. I ran benchmarks (3D Mark) and played Left 4 Dead on highest settings
for an hour, and no issues. I then booted into Linux, and it still happened.
So I then realized I had updated the kernel to 3.13.3 from 3.12.3, and I booted
into the old kernel instead. And now I've been running some "emerges" for an
hour, and browsed the web, without any issues.
Is it possible some weird bug has gotten into the 3.13 kernel? I googled the
issue, and saw that there were several posts about the same behavior on the
Catalyst drivers a year or so back. Even on Windows that is.
