I just installed gentoo-dev-sources 2.6.9 kernel, and immediately after rebooting, and starting X, applications get random mouse click events. If the mouse happens to be over a link, that link might randomly open. When just moving the mouse pointer over the desktop pager, a random mouse event causes desktops to switch. I tried reinstalling ati-drivers, and xorg-x11 as well. No success. This happens frequently enough that X is essentially unusable in this state. However, rebooting into 2.6.8-gentoo-r3 causes the problem to disappear, at least until I try 2.6.9 again. So it definitely seems to be tied to 2.6.9 kernel. Any suggestions appreciated.

OK there must have been an update to the driver for the trackpad on my laptop or something. Suspecting this, I dug out my usb wireless mouse. The problem goes away when I use it instead of the trackpad. Basically any initial touch to the trackpad gets interpreted as a mouse click, no matter how light. I will close this in a day or so, but if anyone has any suggestions in the mean time.
Sounds like interrupt conflict, could you please upload the output of "cat /proc/interrupts" for both 2.6.8 and 2.6.9 kernels. Jeremy, I seem to remember you diagnosing something like this once before, could you please take a look when the info gets posted?
giggles1: Please provide the output of: lsmod cat /proc/bus/usb/devices the relevant section of xorg.conf for your mouse Does this happen using gpm in the console? Can you please try gentoo-dev-sources-2.6.8-r10 as I know that it contained some of the input core updates that went into 2.6.9

hmm... sorry dsd, this doesn't look like something affected by the changes that I helped into 2.6.9 as that was restricted entirely to the USB drivers (hid and wacom). giggles, my advice is to try 2.6.9 rcs to figure out where the change was, then narrow it down to a chanve between two bk's ... then just gradually apply the patches between those bks until you have the minimal patch that introduced the bug. That's basically how I diagnose the kernel problems I run into... tiresome, yes, but I can't reproduce your problem without your hardware, sorry =(
Could you also post the 2.6.8 /proc/interrupts ? Maybe its something obvious that has changed between the two versions..

I'm not sure this isn't as simple as just bad config values for the trackpad sensitivity. I couldn't find any docs for the driver under the kernel source dir. How is it configured?
FYI, I have xorg-x11 6.8.0, 2.6.9 vanilla kernel and a IBM T41 Thinkpad and am seeing the same problem after moving up from 2.6.8.1 vanilla kernel. If I use the built-in trackpoint mouse, it's fine but the touchpad mouse appears to intepret light taps, such as first placing finger on pad to move mouse pointer around, as mouse clicks. It's pretty annoying. This machine uses an ATI FireGL Mobility T2 video chipset.
Strange .. your 2.6.8 interrupts map seems to include both eth0 and eth1, whereas 2.6.9 assigns interrupts to both eth0 and eth1. So, with 2.6.9, are both your network interfaces working? If you disable both network devices (i.e. recompile the kernel without support for your net devices), does it solve your mouse problems?
Oops that didn't make sense. meant to say: your 2.6.8 interrupts map includes both eth0 and eth1, whereas the 2.6.9 one only mentions eth1 with no reference to eth0.
Interesting. Right now under 2.6.9, the r8169 driver is loaded, but eth1 does not show up at all under ifconfig. I usually only use wireless so I had not notcied the missing ethernet device. This synaptics pad is supposed to support tap-to-click. It's never worked at all before this kernel though. I actually like it when it works well, but it's realy interpretting far too many things as a click. I dunno if there's just a driver setting to tweak or if this really is an interrupt problem.
Ok. Could you please test with 2.6.10-rc2, and if the issue still exists, open a bug at http://bugzilla.kernel.org I'm doubting that this is an interrupt issue now, more likely to be a quirk in the touchpad driver. Thanks
