Kernel will freeze x11 session and other issues.

Binary package hint: linux-image-2.6.32-30-generic

I've noticed since I upgraded to, and only while using kernel 2.6.32-32 from package linux-image-2.6.32-30-generic my x11 session will somtimes freeze. I am still able to use the keyboard but selecting things with the mouse or otherwise interacting with the desktop is next to impossible. I don't know if this is related to the kernel, but also since the update if a process like wine or transmission-daemon is killed abruptly i will notice md5sum and deb_md5sum will run without end and my cpu usage spikes to 100% until i reboot the system. Also, when this occurs I am unable to see what PID is actually using that much of my processor. md5sum and deb_*sum show up when this occurs but only run at a "reported 5-15%" resource usage. Booting with the prior kernel resolves the issue. Also, my kernel from that package is compiled as i386 but on a i686 system. I don't know if that has anything to do with it.
