Kernel / Grub Boot issue <SOLVED>

[lwfitz]

So, for maybe the last 4-5 months (I think) I have had an issue where every time I reboot I have to wait 1:30 with a warning that a start job is running for ............ (enter uuid #). The uuid numbers are anything other than my root partition. Including home.

Thinking it might be a hard drive issue I tried a reinstall from the latest ISO and had the same issue. Then I ran a dist-upgrade and all hell broke loose. I got an error regarding initramfs-tools and linux-image-4.6.0-1-amd64.

Finally I got those packages repaired and installed properly. I ran apt-get update & apt-get dist-upgrade and everything came back clean. No errors.

When I rebooted I got to the normal grub screen, hit enter, and was greeted with a lovely flashing cursor. If I boot normally the flashing cursor lasts about 2 minutes, then it goes past and finally hangs without booting up all the way.
If I boot into recovery mode I get the flashing cursor but after two minutes it will go past and get to the emergency mode warning and I can hit ctrl/D and bypass. Once Im booted and logged in Im fine but it takes 2-5 minutes to boot and its annoying.

Any ideas?


SOLUTION

This worked for me

only one really, /etc/fstab.  check to see if it created a swap partition somehow and if so comment it out and reboot.

AFAIK drivers are somewhat troublesome lately... once again.

Try running in no modesetting. When reaching grub press the e key. and in the line that begins with "Linux..." add the following at the end.

For nouveau drivers (Nvidia GPUs) just add nomodeset. It should look something like this:

Code: [Select]

"quiet splash nomodeset"
For Intel cards:

Code: [Select]

"quiet splash nomodeset i915.modeset=0"
if it boots normally then add these changes to /etc/default/grub and to make the changes permanent run

Code: [Select]

sudo update-grub
Sorry, I have zero experience with AMD/ATI cards, but I read they're problematic lately too.

Remove any duplicate entry and/or swap related entry from /etc/fstab and you should be good to go.
Cheers!!!

Hi Jedi  How are you buddy?

Yep, Ive checked this numerous times. None of this makes any sense.


/etc/fstab

Code: [Select]

# /etc/fstab: static file system information.
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>

proc   /proc   proc   defaults   0   0
# /dev/sda1

# /dev/sda3
UUID=18731e08-3798-4358-a82e-09eda6a703f5   /home   ext4   defaults   0   0
# /dev/sda2

I had everything but "splash" so I added that, updated grub and no luck unfortunately.


I guess I couldve given you guys a bit more info. Im on a temporary desktop as I have sold my MSI laptop.

This PC is a Dell Inspiron desktop with an Intel i5, 8gb ddr3, nVidia geforce 610 and 60gb ssd.

Hi there lwfitz,
Make a backup of /etc/fstab and remove the following line from it,

Code: [Select]

UUID=e19086b3-142a-4206-88c1-638353a36cbf   none   swap   sw   0   0
Save the file.
Next run the following command,

Code: [Select]

sudo swapoff --all
Reboot & hope for the best
Cheers!!!

Two items-

First, are you running an NFS or samba server, I know that it can take up to two minutes to shut down if NFS is running, never it stall on startup though.

Second, try a reinstall without a swap file. If you need/want one, pre-partition the disk but leave the partition that will be the swap unused. After boot up use swapon to mount it and leave it mounted when you shut down. If it all works, add the swap partition to fsfab.
,
I've had install issues lately, especially on my older desktop. Same issues you're having. It appears to be related to creating the swap during install. Adding the swap manually post install seems to work, but I occasionally get an error about unmounting the swap partition on shutdown. Leads me to believe this is a systemd issue related to swap file.

I thought the same thing(s) so I did away with the swap partition and removed it from /etc/fstab but that still left the same issue /home partition.

Ive reinstalled with  and without swap and it doesnt seem to make any difference.

I am pretty sure this is kernel related starting in 4.6.0-1 but I dont have any clue how to fix it. MAybe just have to deal with it until things get fixed.


BTW, PackRat I hadnt thought of Samba or NFS. Being that this is a stock install I would think that others wouldve seen a similar issue if it was Samba.

[hakerdefo]

Can you try out the following,

Make absolute sure swap is not in use,

Code: [Select]

cat /proc/swaps

If swap is in use find out the UUID,

Code: [Select]

lsblk -f | grep -E 'swap|SWAP'

Make sure the swap UUID matches the entry in fstab,

Code: [Select]

cat /etc/fstab | grep -E 'swap|SWAP'

And finally check the boot log for errors,

Code: [Select]

sudo journalctl -b -p 3

This should get us something!

Cheers!!!

This, I forgot to point out I have had this issue - but it was for all partitions, not just the swap.

I am pretty sure this is kernel related starting in 4.6.0-1 but I dont have any clue how to fix it. Maybe just have to deal with it until things get fixed.

Is there a way to get an older kernel - like 4.4 series which is long-term support - from backports or something?

Debian Stable is still 3.16, I think. A lot of effort but maybe a netinsall of stable and edit the sources to upgrade to Sid. VSIDO-ize it from there.

[lwfitz]

Heres my boot log

Code: [Select]

luke@montech1:~$ sudo journalctl -b -p 3

This is a fresh install with no swap

Code: [Select]

luke@montech1:~$ sudo blkid

Gonna try and older version and see how bad it breaks things.

Might just have to net install like PackRat said.

So nobody else has had this issue at all? This has been going on for me on two different machines and starts on a fresh install

I have now installed yet again and when updating held back initramfs-tools and linux-image-4.6.0-1-amd64

Finally after all the updates were installed I was able to install linux-image-4.7.0-1-amd64 (I thought it might be kernel related)

removing swap fixes one error but /home still errors and systemd seems to be unable to mount it properly

Im not sure what else to try at this point.

[lwfitz]

Solved!

Im not sure wtf was going on I just figured out how to get around it.

It appears to have been a systemd issue so rather than fight it anymore I just did away with systemd and went back to sysvinit. Please someone tell me why I will regret this. I dont see any downside but I could be wrong.

Heres what I did and it seems to have fixed all my issues

Code: [Select]

sudo apt-get install sysvinit-core sysvinit sysvinit-utils
Reboot

Then remove systemd

Code: [Select]

apt-get remove --purge --auto-remove systemd

And stop systemd from being installed later on

Code: [Select]

sudo su

Code: [Select]

echo -e 'Package: systemd\nPin: origin ""\nPin-Priority: -1' > /etc/apt/preferences.d/systemd

I won't be the one. 

OpenRC everywhere here. VastOne wrote an specific switching guide for Vsido somewhere in the forum. But the essentials work for any Debian and from Jessie to Sid. Tested several times.
