No TPM chip found, activating TPM-bypass!

[phoenix89]

When trying to install fedora, I frequently run into the problem where it locks up on boot.

The line that I am able to read right before it locks up is:
"No TPM chip found, activating TPM-bypass!"

I was wondering if anyone has any similar problems or any ideas on how I could fix this.

Do you have a TPM Chip?

I don't think so. I am using a ASUS F50SV laptop.

So it is not an error. I think, I could be wrong though.

My problem is that when booting up the system locks up at that line and is completely unresponsive and I am trying to find out if there is any work around, for it.

Yes, it is not an error message, it is just the last line that I can read before my system become completely unresponsive.

tpm_tis.interrupts=0

Adding "tpm_tis.interrupts=0" into /boot/grub/grub.conf file solves the
problem.

I am running into the same problem when trying to boot from the fedora 13 live cd. Is there
a workaround for this too? Because I don't think there is a way of editing grub before
installation...

I just want to try fedora out on my laptop without installing anything, to see how well the
webcam works and other stuff too.

Yes - you can edit the line, but you will have to press the "tab" key at some point
between the BIOS completion and before Linux takes over. Once you get the grub
display you should get some directions on how to edit the boot line.

I had to boot several times before I got the timing right (I really wish it had a 5-10
second timeout before it boots, AND ban the use of the "hidden" option during
installation).

thanks, already figured that out actually. I edited that same line all the time, to add the
noacpi option and to delete the quiet rhgrb.

Now that I added tpm_tis.interrupts=0 nothing changed, while booting up I still get the
message "no tpm chip found, starting tpm bypass" and the whole system stops responding.
Only way to turn off is the power button.

Tried out the Debian live cd and it worked, I could boot just fine without editing the grub options. Seems 13 isn't
such a lucky number for a distribution, eh? : P

Are there any news on this issue? Has someone got Fedora 13 to boot without that nasty error about TPM?
