What steps will reproduce the problem?
1. build L27.12.1-P2_Gingerbread_pandroid_rls_v2 with tpm and tpm_tis kernel module
2. load the tpm kernel module insmod ./tpm.ko
3. load the tpm_tis kernel module insmod ./tmp_tis.ko

What is the expected output? What do you see instead?
When I try to load the tpm_tis kernel module sometimes the whole system freezes or I get the following output from dmesg:
