So it looks like this is fixed by v3.3-rc1~105^2^2~13^2~4 (tpm_tis:

Jurij, what kernel were you testing against?

It would be nice to pass this to Greg for inclusion in 3.2.y and
perhaps 3.0.y kernels.  Do you know if 3.0.y is affected?  (If this
patch is tested against something close to upstream 3.0.y or 3.2.y,
I'll be happy to submit it to stable@).
I experienced the hangs with Debian's 3.0 kernel, too.
Does the Debian 3.0 kernel contain a function probe_itpm in the
drivers/char/tpm/tpm_tis.c driver? If not, it would be a different
problem you are seeing.
I looked again at my grub menu, and it's 3.2-rc and 3.1 that were
affected. 3.2-rc triggered more reliable.

(probe_itpm was introduced to drivers/char/tpm/tpm_tis.c in

	9519de3f (tpm_tis: Probing function for Intel iTPM bug)

. That is it hit mainline for v3.1-rc1.)

I take it's not a problem in a Debian 3.0 kernel (since the culprit patch only appeared in 3.1-rc1). We will submit the relevant patch(es) to the 3.2.x stable kernel.

Thanks and regards,
