Hello,

I'm using kernel 2.6.26-rc6 at the moment and with it dimming the display is slow and laggy. Using kernel 2.6.25 doesn't show this problem.

Here is a more detailed explanation:

I'm dimming my display with the appropriate keys on my laptop (Fn + right/left). Till kernel 2.6.25 this has worked without any problems. Now I'm using 2.6.26-rc6 and using the keys the display is dimming much slower and also laggy. By laggy I mean if I hit the keys for increasing/decreasing brightness it starts dimming and when I release the keys after some time it still continues dimming for some steps.

My laptop is a Acer Travelmate 661lci and has an Intel 855 chipset.

I'll attach my dmesg output, please tell me if you need any further information.

Think you forgot the dmesg. Are you seeing a "ACPI: EC: GPE storm detected, disabling EC GPE" message? See:

http://bugzilla.kernel.org/show_bug.cgi?id=10724

This seems to affect a lot of Acer laptops.
