Bug Description

[Impact]
Some systems fail during boot, possibly because of TPM interrupt storms.

[Test case]
Test that systems boot and look for TPM dmesg messages implying probe is OK.

[Regression potential]
TPM in some systems fail to probe, which is better than not booting.

------------------------

Kernel 5.3.0.-23-generic and
Kernel 5.3.0.-22-generic

don't boot, I get the "Loading initial ramdisk ..." on purple background, nothing happens, Notebook need to get shutoff to resume
Kernels:
5.3.0-19 and
5.3.0-18
do work

It's a Lenovo L580 Running Ubuntu 19.10

Hi Eugen - Thanks for the bug report and sorry about the trouble you're experiencing.

I'm trying to figure out if there is any link between a few different bug reports that I'm seeing come in for 5.3.0-22. It looks like the dm_crypt module is loaded on your system so I'd like for you to verify here that you use full-disk encryption with LUKS/dm-crypt. Thanks!

Eugen (netzwerkdude) wrote on 2019-11-15:

Hi Tyler,

Yes, LUKS/dm-crypt is running - I've used the options in the OS installer to encrypt the drive

Andrey Kadatsky (akadatsky) wrote on 2019-11-15:

I have the same issue:
Lenovo Thinkpad e590 and full-disk encryption(it asks password during boot).
Also, it works on 5.3.0-19 (and previous) and does not work with 5.3.0-22+.

In my case I see this 2 lines in a loop during boot:
WARNING: Failed to connect to lvmetad. Falling back to device scanning.
Reading all physical volumes. This make take a while...

But I'm not sure how to check do I use LUKS/dm-crypt, cause I got a laptop with already preinstalled OS.

Can you add the output of updating the initramfs? And also try 5.3.0-24 from eoan-proposed?

The initramfs update command would be like:

sudo update-initramfs -u -k 5.3.0-23-generic

I am trying to sort out if this is related to LP: #1852521, where a keyfile was used.

Hi,

here is the output of

I: The initramfs will attempt to resume from /dev/dm-2

(for 24 it's the same)

also 5.3.0-24 from eoan-proposed doesn't work either

Had to remove the old 5.3.0-24 first - but okay, now it boots properly with your posted kernel version.

Do you need any additional logs for comfirmation?

Any logs you can produce about the TPM could be helpful.

sudo dmesg | grep -i tpm

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-eoan' to 'verification-done-eoan'. If the problem still exists, change the tag 'verification-needed-eoan' to 'verification-failed-eoan'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

@alvarofernandoms maybe your case is different. Please file a new bug instead, add following kernel parameters and take some pictures when your systems hangs:

initcall_debug ignore_loglevel=1 earlycon=efifb

And don't forget to remove the default parameters "quiet splash".

Hello everyone. The problem still here using Dell 7567, even in Ubuntu 20.04 kernel 5.4. But, following the suggestion of @danielgrebe in another bug report, I was able to boot after switching PTT Security off in BIOS. Thank you.
