Boot time when linux-firmware-* have new versions

OpusOne · 2025-07-11 19:40:24

Hi all,

I noticed that when there are updates to linux-firmware-* along with a new kernel version, the subsequent boot is much longer than usual. But I see no particular delay in dmesg. Is that normal?

Not a problem, just to understand the boot process better and if it's to be expected.

Does the delay happen in userspace? Checked the system journal?

systemd-analyze critical-chain

?

This is what it gives:

But that's not from a slow boot, is it?
What does the journal of a slow boot look like?
