Well, that's kernel fault, not mine! ;-)
Looks like it doesn't find the TPM itself...
My own dmesg shows something like this:
[ 70.164382] tpm_tis 00:09: 1.2 TPM (device-id 0x0, rev-id 78)
Can you find something like that in yours?

I just enabled Kernel logging to go to a file and got the following
output for the TPM:
tpm_tis: probe of 00:0b failed with error -5

tpm_inf_pnp: probe of 00:0b failed with error -22

Klogd is running but it looks like I don't have a Kernel log in
/var/log and I don't get anything out during initiization. How do
I check the device driver for errors?

It can't open the TPM device. So, you gotta check the TPM
device driver for errors.
Any interesting message in the kernel log or during
initialization?

I recompiled TrouSerS with debug and ran it with strace and
received the following output:
open("/dev/tpm0", O_RDWR) = -1 ENODEV (No such device)
open("/udev/tpm0", O_RDWR) = -1 ENOENT (No such file or
directory)
open("/dev/tpm", O_RDWR) = -1 ENOENT (No such file or directory)

Can you open the /dev/tpm0 device file?
If not, try to use the strace command to execute
trousers. Something like this: strace /usr/sbin/tcsd -f
Among the lines printed, should be something like this:
open("/dev/tpm0", O_RDWR) = 3
The number after the equal sign is the return value of
the syscall. If it's -1, then your problem is with the
TPM device driver or the TPM device itself.
Otherwise, you will need more information, so I suggest
you build TrouSerS from its source and enable debugging.
(./configure --enable-debug)

I checked netstat and the default port isn't in use. I
ran tcsd in the foreground and teceived the following
error: TCSD TDDL ERROR: Could not find a device to open.
Before running tcsd I run:
Modprobe tpm
Modprobe tpm_bios
Modprobe tpm_tis force=1 interrupts=0
I ran modinfo on tpm_tis and my decice appears (pnp:
dIFX0102*)
I also have tpm0 listed in /dev and the TPM is enabled
in the BIOS so I'm not really sure where this error is
coming from.

Check if the port used by TrouSerS (default is
30003) is not in use.
'netstat -ant' will provide you with the list of TCP
ports being used in your machine.
Also, you can execute TrouSerS manually from the
command line using this line: '/usr/sbin/tcsd -f'
This will put TrouSerS on foreground and let you
know what kind of error is being generated.

Hi,
I'm trying to get the TCSD daemon started which it
says it starts successfully but it looks like it
crashes immediately. I try /etc/init.d status and
it comes back with tcsd dead but subsys locked. Any
idea on what could cause TCSD to crash so quickly?
Thanks
