Hi, Definitely seems to be a kernel issue. You have a lot of "strange" kernel modules loaded, to say the least.
I am running the latest Hardy kernel 2.6.24-12-server [which gives me *lower* wakeups than the -generic kernel, but both kernels give under 500 wakeups per sec under heavy load] on a ThinkPad X61t. Since our hardware is pretty much the same except for the graphics and your faster processor, I think it shouldn't be too much of a stretch to ask you to trim down your modules to the bare necessities for running your hardware. For example, those virtual machines (kvm and virtualbox) could be doing _anything_ behind the scenes, causing egregious interrupts. I have done a diff between our two lsmods (after sorting the modules by name) and determined that you have loaded the following modules that I have not. I think you should remove them and see if your wakeups go away; then, try to isolate the particular module that's the problem: [kernel mode virtual machine] kvm kvm_intel [fat32 and reiser filesystem drivers] reiserfs vfat [SHA256 crypto] sha256_generic [SCSI emulation for your cd-rom] sr_mod [thinkpad embedded controller?!] thinkpad_ec [extra usb device modules] usbserial usb_storage [VirtualBox] vboxdrv [Related to wifi/ACPI?!] wmi_acer I would suggest you start by removing these. Some are more likely to be the culprit than others - you probably don't have to worry about the crypto routines or filesystems. I'm very suspicious of the virtualization (vbox and kvm) though, as well as curious about thinkpad_ec. Also, is there any reason why you do not have thinkpad_acpi loaded? Anyway, you could go to single-user mode (sudo telinit 1) and kill all processes, like you did before, and just start removing modules until there's basically nothing left, running powertop after each modprobe command. If you get down to modules absolutely required for system operation (such as the filesystem drivers) and still have the wakeups, then the wakeups might be in the monolithic part of the kernel, which is even more surprising.
