[SOLVED] Boot process slowdown because of /dev/tpmrm0 start job.

Hello! After recent update of the system I started getting this problem. Because of this job starting, I gave to wait extra minute during boot before it times out. It persisted for a few days already, and I never had problems with that thing before. I think that systemd tries to use my tpm module, but as I understand I don't even have one in my machine. (Using `cat /sys/class/tpm/tpm*/tpm_version_major` from ArchWiki yields no result.)

I guess I just need to disable it, but I didn't find any configs related to this.

journalctl -b --grep=tpm

Solved by masking tmp2.target.

Typo: tpm2, not tmp2 smile

I'm very thankful for your comment, this did the trick for me!

Re: [SOLVED] Boot process slowdown because of /dev/tpmrm0 start job.

Sorry for the noob follow-up question is this really a fix or are we masking the error (excuse the pun)?

>>> sudo dmesg -k | grep tpm                                                                                                                                   19:03.56 Mon Jun 24 2024 >>>

Re: [SOLVED] Boot process slowdown because of /dev/tpmrm0 start job.

I also ran into this big drag of a boot time after some updates on one of my machines. I looked at the systemctl manual and searched for "mask" to find the answer to above question:

>Completely disabled, so any start operation on it fails (permanently in /etc/systemd/system/ or transiently in /run/systemd/systemd/).

In short, it's similar to disabling a systemd service, but "disable" does not work in this case.
