Is everyone who is seeing this issue using an Intel graphics device and using UXA?

I'm using Jaunty, with a 2.6.30 kernel (from the kernelteam PPA) and X and Intel drivers from the xorg-updates PPA. (xserver-xorg-video-intel=2.7.1). I also appear to see this issue (many interrupts) as described by the OP. Because I am using 2.7.1, I'm able to switch back to EXA; the extraneous interrupts disappear and in particular I get normal battery life again.

I believe the xorg-video-intel 2.8 driver in Karmic still supports XAA (EXA support has been removed). Could those affected try XAA (yes, the performance will be terrible) and report whether the extraneous interrupts exist?

For this bug to be fixed, it's extremely important to keep it on-topic. In particular, limiting discussion to configuration similar to the reporter (Intel graphics & UXA). Political discussions (e.g. what Ubuntu's priorities are, whether this bug is important, etc) should also be done elsewhere.
