Bug Description
After updating the kernel to 2.6.35-24, suspending the computer doesn't work most of the time. The screen goes blank, but the sleep LED is blinking all the time, and it doesn't suspend. It usually works to suspend the first time after a boot, but the second time always fail. Sometimes the first time fails as well.
Booting up with 2.6.35-23 I can suspend many times without any problems.

Essentially, disable the tpm_tis kernel module.
