Default TPM 1.2 and Kernel 2.6.32.43

Hi list,

I'm using Ubuntu Server 10.04 LTS (amd64) with 2.6.32.43 #1 SMP x86_64
GNU/Linux.
Additionally, I have a TPM 1.2 module on the mainboard which I can
activate in Bios.


Unfortunatley, I'm not able to use the TPM module, because it times out:

toor@node-4:~$ dmesg | grep tpm
[ 2.524876] tpm_tis 00:0e: 1.2 TPM (device-id 0xB, rev-id 16)
[ 2.982272] tpm_tis 00:0e: Operation Timed out
[ 3.922214] tpm_tis 00:0e: Operation Timed out
[ 14.632849] tpm_tis 00:0e: Operation Timed out

toor@node-4:~$ tpm_selftest -l debug
Tspi_Context_Create success
Tspi_Context_Connect failed: 0x00003011 - layer=tsp, code=0011 (17),
Communication failure

Tspi_Context_FreeMemory success
Tspi_Context_Close success

I read about some problems with the kernel and the TPM module..
http://markmail.org/message/c2nld4lh7aji5jce#query:+page:1+mid:c2nld4lh7aji5jc e+state:results

Is there maybe a workaround available?
Or can anyone help me to solve that problem?

Thank you!

Seb
