After the ACPI patch from 2.6.17 was added to 2.6.16.1 in testing with PKG rel 2, I have experienced lag in all aspects of the OS. For example, when starting X, the NVIDIA logo usually flashes for less than a second, but with this patch it now hangs around for 5 or more seconds. Opening menus also lag, not much, but it if definately slower than normal. glxgears also reports a drop of around 600 FPS.

To test my theory that it was the ACPI patch, I grabbed the latest PKGBUILD (2.6.16.1-4) and all the rest, with abs, and built the kernel without the ACPI patch and it worked. Speed is now back to normal.

some strange entries while booting in dmesg?
sorry here the patch doesn't hurt so some debugging could help to fix this.

I'm not exactly sure what I am looking for, as I don't know what is "normal". :)

Therefore, I have attached two log files, the 2.6.16.1-4.txt is the kernel from current, obviously, and 2.6.16.1-5 is my custom built kernel.
