Suspend broke in 2.6.35-25

[Greg Grossmeier]

Lenovo x200s
Suspend/Resume works in 2.6.35-24 just fine.
It broke in 2.6.35-25. Will not suspend.

See attached screenshot of the error messages when I ran pm-suspend from VT1 after booting with no_console_suspend (as per https://wiki.ubuntu.com/DebuggingKernelSuspendHibernateResume section on suspending from text mode)

I have had a similar issue with my T500 since upgrading to the same kernel release. I noticed in your boot dmesg the errors that I've been focusing on...

[ 4.531330] tpm_tis 00:0a: 1.2 TPM (device-id 0x1020, rev-id 6)
[ 4.551294] tpm_tis 00:0a: tpm_transmit: tpm_send: error -5
[ 4.571865] tpm_tis 00:0a: tpm_transmit: tpm_send: error -5
[ 4.598088] tpm_tis 00:0a: tpm_transmit: tpm_send: error -5

To test if tpm_tis is the culprit you can unload the tpm_tis kernel module for the current session with:

$ sudo modprobe -r tpm_tis

After this I was able to suspend successfully from the session menu (icon looks like a power button in the upper right panel in the default gnome desktop UI).

Here's a related post that suggests the source of the bug and recommends a solution:
