Hi Lavina, did you compile the TPM into the kernel or is it loaded as a module? It must be compiled into the kernel. IMA requires the TPM to be available early at boot time before modules can be loaded.

Date: 05/09/2008 06:49 AM Subject: [Linux-ima-user] no TPM chip found Hi, I compiled new kernel with ima support by applying ibm-ima-patch-2.6.22.9.patch and following the instructions in the INSTALL file. I am able to boot the new kernel, but it cannot find the TPM chip on my laptop. The output of "dmesg | grep IMA" is as follows: [ 5.360000] IBM Integrity Measurement Architecture (IBM IMA v8.3 10/09/2007). [ 5.360000] IMA (test mode) [ 5.360000] IMA (TPM/BYPASS - no TPM chip found) I am using Lenovo X61 laptop that has Atmel TPM chip. I am able to talk to TPM using trousers and tpm-tools. Commands like tpm_version are working. Modules tpm_bios, tpm and tpm_tis are loaded. Any ideas why IMA cannot find the TPM chip?
