  • Warning in Kernel


    I recently upgraded my desktop to Xorg7.2 + Compiz. I enable AIGLX and Composite (I must say this, cube is really cool), after playing around with the system, I notice this warning message from the kernel:

    Anyone encountered this before? So far, I don't feel my system is being affected by this. However, I just want to be sure...

    Anyway, I am using Pentium D 2.6GHz + 1G ram. Distro: Slackware (using latest current tree). Kernel: 2.6.22-rc4
