Long boot times due to device timeouts after motherboard changes

After changing my motherboard, booting my system one time and then updating my UEFI firmware systemd-analyze blame shows me a lot of nvme device units with long run times. My system is using systemd-boot and an encrypted LUKS1 root/swap partition. Those are referenced by /dev/mapper/root and /dev/mapper/swap in /etc/fstab. My kernel cmdline looks like this:

rd.luks.name=e3b81371-df48-4716-aa6e-bf4c85736078=root rd.luks.name=7001dea1-8496-4577-b50f-5cffebeddb11=swap root=/dev/mapper/root resume=/dev/mapper/swap rw quiet splash

systemd-analyze blame shows me:

1min 5.177s sys-devices-pci0000:00-0000:00:02.2-0000:14:00.0-nvme-nvme1-nvme1n1-nvme1n1p3.device

... even more for every nvme device and partition I have (I have 2 NVMEs)

I’m not quire sure what’s going on. Any ideas?

Motherboard: MSI Pro B850M-P Wifi
Bios version: E7E71AMSI.1A44
Bios build date: August 5th 2025

Just a few quick thoughts;

  • Did you reconfigure your BIOS to suit your hardware?
  • Did you check your /etc/fstab to make sure all UUIDs match that of your actual disks?
  • Did you check that the “resume=UUID=” UUID in /etc/default/grub matches that of your swap partition?

Please provide system information as described (below) to help others identify other possible contributors.

Welcome to the Manjaro community

As a new or infrequent forum user, please take some time to familiarise yourself with Forum requirements, and the many ways to use the forum to your benefit:


Update Announcements

The Update Announcements contain important information and a Known Issues and Solutions section that should generally be checked before posting a request for support.

System Information

While information from *-fetch type apps might be fine for someone wishing to buy your computer, for Support purposes it’s better to ask your system directly; :eyes:

Output of the inxi command (with appropriate parameters, and formatted according to forum guidelines) will generate information that may be useful for those wishing to help:

inxi --filter --verbosity=8

or the short form:

inxi -zv8c0

Be prepared to provide output from other commands whenever asked. It’s equally important to provide as much actionable information as possible in your first post, rather than simply indicating there is a problem.

I’m sorry but I don’t feel comfortable to put as much information about my system as inxi --filter --verbosity=8 does . If you need anything specific let me know and I’ll post the results.

I’m using systemd-boot btw. I first thought that grub might be the culprit so I replaced it with systemd-boot.

Yes I did cross check the UUIDs, they match my kernel cmdline (see my first post). About UEFI settings: I didn’t really enable anything special in the previous motherboard except enabling Intel XMP and AMD Expo on my new one.

/dev/mapper/swap swap      swap    defaults,noatime 0 2

The NVME is initialized by the UEFI and then handed over to the kernel. If, for whatever reason, the initialization takes longer than expected or is not triggered, systemd waits until the device finally responds or not.

One possible cause could be “fastboot,” as it can also skip the NVME. Another possible cause could be slow wake-up / switching from power-saving mode.

I couldn’t find any option for fast boot (Intel only?) and I’m booting from cold so no power-saving mode (if that’s what you meant).

This might go a little more smoothly if you provide the system information requested, and logs;

The idea is to provide that information to help others identify anything that might be contributing. Help us to help you.

Regards.

Kernel 6.15 reached EOL around two weeks ago.

It is recommended to replace it at the earliest opportunity, as updates for this kernel are no longer provided from the official Manjaro repositories.

You could either use kernel 6.16, or as is often recommended, the latest SLTS kernel – Kernel 6.12 (LTS) – which isn’t expected to reach EOL until 31 Dec 2026.

See Manjaro Kernels for information on how to manage your kernels.


Otherwise, I see nothing obvious that might contribute to an excessively slow boot.

What length of time is it that you are you calling “slow”?

Perhaps system logs (requested earlier) might reveal something.


Regards.

Try journalctl -b0 | grep nvme for nvme-related log messages or journalctl -b0 -p3 for all errors.
