Since upgrading from 13.10 to 14.04 (with do-release-upgrade) my computer (Sony vgn-sz1vp) hangs for 4 minutes when booting. 

[    1.015598] tpm_tis 00:06: 1.2 TPM (device-id 0xB, rev-id 16)
[    1.019920] ACPI: Battery Slot [BAT1] (battery present)
[    1.321725] isapnp: No Plug & Play device found
[   93.668058] random: nonblocking pool is initialized
[  121.040029] tpm_tis 00:06: Operation Timed out
[  121.052385] tpm_tis 00:06: A TPM error (-62) occurred attempting to determine the timeouts
[  241.088029] tpm_tis 00:06: Operation Timed out
[  241.100484] tpm_tis 00:06: Could not get TPM timeouts and durations

So far I have tried:

  • enabling and disabling TPM in the BIOS (no change)
  • adding blacklist items for tpm_tis (and other TPM modules) in /etc/modprobe.d/blacklist-local.conf (no change)

Is there a boot parameter I can add to grub to tell the kernel to stop trying to communicate with the TPM hardware?

Press 'e' at boot menu. Add the command nolapic after ro in the boot options. You can add this to grub file:

Edit your grub.cfg and change

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

to 

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nolapic"

Save file, then run update-grub.

Modifying the following lines in my /etc/default/grub file has solved the problem:

GRUB_CMDLINE_LINUX_DEFAULT="acpi=nomsi quiet splash"
GRUB_CMDLINE_LINUX="tpm_tis.interrupts=0"

tpm is compiled into the stock Ubuntu kernel, so there is no way to disable it completely with a boot parameter or by blacklisting.

To resolve this issue on a Vaio SZ3 with Linux Mint 17 (based on Ubuntu), I had rebuild the kernel with tpm disabled, as follows:

Follow BuildYourOwnKernel for the basic process, with the following additions:

  • Run the menuconfig step as described in 'Modifying the configuration'. Select Y to edit the 'i386 generic' or 'amd64 generic' configuration (N to all others). Once in menuconfig, use the / command to search for CONFIG_IMA, press 1 (or whichever number is indicated) to navigate to it, and N to disable it. Do the same for CONFIG_TPM. I also disabled CONFIG_DEBUG_INFO to reduce the disk space required for the build.
  • Before building, touch debian.master/abi/i386/ignore (or amd64) to disable the ABI checks, which would fail due to missing TPM and changed hashes (if you disable CONFIG_DEBUG_INFO like me).
  • Before installing the .debs that are built, you may need to sudo apt-get install linux-tools-$(uname -r) linux-tools-common

Bear in mind that you'll need to prevent the kernel being automatically updated in future, or go through this process again with the new version.

I've run into the same thing and this fix worked like a charm

# edit /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash tpm_tis.force=1"
