There are also ongoing sound problems in >=linux-3.2 including the latest 3.3 git. I didn't catch that at first, because I don't use my internal mono speaker too often - that one is broken - while the headphones output on notebook and docking station work fine.


seems like I also experienced some kind of issue with sound on the Intel HDA driver when coming back from suspend

only certain stuff seems to work (youtube) - other things not

might be an app/youtube-related issue though

Both 3.2 and 3.1 are unstable on my AMD Opteron. The video always seems to crash within a day. This is using an AMD HD 4870 and the ati-drivers.

When it crashes, one CPU core goes to 100% and whatever process the video card was using refuses to die even with 'kill -kill' by root. Even a reboot fails. I have to physically shut it off and then I have hard drive corruption that needs to be fixed. No problems with 3.0 on the AMD.

No apparent problems with 3.2 on an E7600 or 3.1 on an E2160, both using the nvidia-drivers for the video cards.


I rather suspect that it's more related to ati-drivers

remembering having had these kind of issues while I still used fglrx

more often when using compositing (compiz-fusion, compiz++, kwin + compositing) and/or adobe-flash & youtube videos or flash animations


which filesystem is it ? ext4 ? btrfs ?

try using xf86-video-ati if it's possible and whether it still happens,

there's however also some slight instability when using compositing and opengl or videos for some longer time

but by far not as much as with ati-drivers


hope that helps

The reason I bought this card is to use it for GPU crunching at the Milkyway@Home project. Hence, I require the ati-drivers. I use ext3 for '/', reiserfs for portage, xfs for distfiles and ext3 for my boinc (milkyway@home) partition.

What would be the difference between 3.0 and 3.1/3.2 that would cause the onset of the crashes? Is there perhaps something in the kernel I can enable/disable to be more stable?

When it crashes it also causes the loss of keyboard and mouse. It doesn't appear to have any affect on anything network related. I can usually ssh in after the crash.

This computer performs only 2 functions. It's an mp3 server and a boinc client. I suppose, when I get home and am able to restart it, I can check access of the mp3 server and see if it's could possibly be related in some way. The mp3 server has a web interface. (gnump3d)

this sounds like some issue with the graphics driver - you by chance have some compositing window manager active ?

I tended to get this with kwin or compiz enabled,

but for me it was a (supposedly) hardlock where even magic sysrq key didn't work

does magic sysrq key work in your situation ?

I haven't tested to ssh in my case so I can't tell for sure if I had the same situation,


try tinkering around with the graphic-driver switches in xorg.conf - that usually helped me to get things a tad more stable but fglrx is still more unstable (e.g. randomly hardlocking with compositing enabled + flash, hardlock with flash or the screen freezing, screen staying black with some driver releases, ...) than the xf86-video-ati driver

so I had enough and switched permanently to the OS driver


there could also be the possibility that when the memory (RAM, cache, etc.) gets very full that the graphics driver doesn't likes this ...

hope that helps in some way

I think it was much simpler than all that. I think the Ram was overheating. I've swapped the card out until I can put some heatsinks on the Ram. When I started crashing even on 3.0 it kind of clued me in. I guess these factory OC'ed 4870's weren't designed to be full blast full time.
