Hi! Sadly, I have to say that I'm totally oblivious to power-related stuff both in software and hardware, so I have no idea what you are asking or proposing.. :)

I don't know if you have access to the files I've included in the bug report, so here are the links to them:

Regarding the syslog during boot, is that the same as the BootDmesg I've attached? Or should I search in another log file?
I'm not sure about the model, but I was hoping you could deduct something from the UdevDb or the lspci output above.

Error 62 is ETIME. The driver is timing out during a tpm_send,
possibly trying to send the Tpm_SaveState command.

It may be that you cannot talk to the TPM at all. Have you tried
sending messages to the TPM before suspending?

Are there any other tpm entries in the syslog? Like at boot?

What model TPM is it?

Hi Rajiv,

Not sure if I should send this to you, please kindly forward it to the
appropriate person if not, thanks.

Peter has encountered a problem during suspend, the tpm_tis driver's
suspend callback will fail, the relevant message is:

And the problem has been there since v2.6.32(shipped in ubuntu 10.04),
and the latest upstream tree(v3.9-rcx) also has this problem. The bug
link is here:

Please feel free to ask for more information, thanks.
