[SOLVED] Kernel 5.3.18-3 - No boot - loading initial ramdisk hang

[DerGraf]

Hello,

after months i had to do a PVE reboot yesterday.
All updates was installed, kernel 5.3.18-3 as well. But kernel 5.3.18-2 was still running.

On reboot, machine hang by "loading inital ramdisk". I try starting several times (also with 10 minutes waiting).
By manual selecting 5.3.18-2 machine boot up an works as always.

Now i have downgrade by "apt install pve-kernel-5.3=6.1-5" and remove faulty kernel by "apt remove pve-kernel-5.3.18-3-pve" and all is fine.

Whats the Problem?

My machine is based on Asrock J5005. PVE was installed in 2018 as LVM Setup. Storage are 2 SSD (md0 - raid1) and 2 HDD (md1 - raid1). iSCSI (Target-cli) and Cryptsetup (i have 1 encrypted LVM partition) is installed also. But this works all by now.

I cant find any logs at this boot time.

Thanks für help.

you could try to boot it again, but modify the kernel commandline (hit 'e' in grub where the kernel gets selected and edit the line starting with 'linux' ) - maybe this could provide more information.

Apart from that - you could also try installing and the 5.4 kernel series (it will soon become the default for PVE 6.x anyways - so maybe that would be a future-proof fix):
`apt install pve-kernel-5.4`

I hope this helps!

Thanks for answer.
Will try it next weekend and report. Hope it works with 5.4

5.4.34 works

But there is an other problem. I cant upgrade other components because PVE Update still want to install pve-kernel-5.3
PVE update say my current version is 6.1.5 and want to upgrade to 6.1.6
Why? And how to solve it?

Thanks for help

I´m afraid to run upgrade

I´m afraid to run upgrade

Why? - The output looks pretty ok to me? (like a regular upgrade)
The one thing that changed recently is the release of PVE 6.2 which by default pulls in the 5.4 kernel (one of the new packages being installed)

I hope this helps!

 

[DerGraf]

I´m a brave boy and run upgrade.
After Upgrade i´m up and ready. No kernel issue.

Thanks for help
