[Trustedjava-support] TPM Disabled

[Adam P. <Ada...@gm...>]

Hello,

I am working with a TPM 1.2 chip (Infineon 9635).  I was wondering if
anyone has been recieving a "TPM disabled" error message while running
trousers.  I am using the tpm_tis kernel module, primarily because I
can not get the tpm_infineon kernel module to load on my system.  On
an aside, when I try to load the tpm_infineon k. module, the kernel
does not associate the loaded module with my tpm.  I am using FC5,
Linux Kernel 2.6.18, and I load the module with: 'modprobe tpm_tis
force=1 interrupts=0', which forces the module to load and disables
the interrupts.  My system Mainboard is a MSI K8NGM2-NBP with an AMD
64X2 processor.

When I start trousers, I do the self test and that will execute with
no problem, but any other commands (e.g. tpm_takeownership, tpm_clear,
etc.) will result in the following error:
   Tspi_TPM_ClearOwner failed: 0x00000007 - layer=tpm, code=0007 (7),
TPM is disabled

Below is the context of the message:
# tpm_takeownership
