Bug#852804: linux-image-4.9.0-1-amd64: tpm_tis kernel stack overflow on Lenovo T61



Some additional Info and a workaround:

I forgot to mention that i don't use the TPM-Chip. In fact it was
disabled in the BIOS. And yes: I have tried to turn it on and off again.

Booting with the recent 4.8 Kernel i get something like that in the
dmesg:
  tpm_tis 00:05: 1.2 TPM (device-id 0x3203, rev-id 9)
  tpm tpm0: tpm_transmit: tpm_send: error -5
  tpm_tis 00:05: Could not get TPM timeouts and durations

So i get an error message, but no oops or the like. Everything works
as expected.

As a workaround i booted with the option "tpm_tis.interrupts=0".
No stack overflow occurs with this option on the 4.9 kernel anymore.
So, if for some reason this bug can't get solved, anyone who runs in this
issue should place a
  GRUB_CMDLINE_LINUX="tpm_tis.interrupts=0"
in his/hers "/etc/default/grub", run
  update-grub
and should be fine.

Hth, niels
