The following is a snippet from dmesg.

I have kernel-gentoo-2.6.8-r3
How can I fix this? What exactally is wrong? It seems to be related to my ati-drivers?

| IMHO nothing, you just enabled a kernel debugging function called "spinlock sleeping" IIRR. I just disabled it and had no problems so far. |

Your right. I checked my linux/src/.config file and found that under kernel hacking I had Sleep-inside-spinlock checking included.
So you don't think that the fact I have a function being called from an invalid context is anything to worry about?
What about the Spurious ACK lines...

Is that anything to be concerned about?

I use the binary ati driver and had no issues with the newer ones (>=3.11) in combination with xorg-x11 6.7, and even if I had it's binary distributed only, no chance to change the source and recompile.
The atk.c issue is reported to vanish when using xorg-x11 IIRR. |
