Slow Boot

[Snowhog]

I think you might find the cause and solution here.

NOTE: I re-installed grub and the "partition table is out of whack" warnings have disappeared. Very nice.

I don't think it's the btrfs driver loading that's the delay. It's the line after.

Now you tell me

The output of blkid is:

I'll check Snowhog's suggestion and report back.

No luck.
I installed rng-tools.
Ran sudo update-initramfs -u and sudo update-grub.
Still 30-seconds lag.

not@all:~$ sudo update-initramfs -u
update-initramfs: Generating /boot/initrd.img-4.18.0-22-generic
I: The initramfs will attempt to resume from /dev/sdb5
I: (UUID=bbb7dbfc-e767-43c9-8b99-614bbaab2cc5)
I: Set the RESUME variable to override this.

Now, /dev/sdb5 is a swap partition... you have my blkid just above.
And it seems to be correctly referenced in fstab:

UUID=bbb7dbfc-e767-43c9-8b99-614bbaab2cc5 swap           swap    defaults,noatime 0 2

So, whatever... one thing. It says "Generating /boot/initrd.img-4.18.0-22-generic". My running kernel is reported (by inxi) as 4.18.0-21.
Now, that is a bit weird, isn't it?

sudo update-initramfs -uk all

[Don B. Cilly]

That one definitely did it
Thank you.

It now boots really really fast. Very nice.
I wonder what the kernel mix-up is due to... I have some vague ideas, I'll investigate.
