[Solved] 4.20.6: Freeze during boot (before graphical interface)

Hello everybody,

I got a new notebook and am using the same ssd that I was already using for my old notebook. At first I was not able to boot as the boot process froze before the graphical interface was reached (even switching to a console was not possible). During testing I noticed that it seems to be related to the kernel version. On the ssd the current kernel 4.20.6 is used but the Arch Linux install image that uses 4.20.0 boots just fine (without graphical interface at first). So I copied the kernel from the install image onto my SSD, also copied the modules and regenerated the initcpio image (from within an arch-chroot). Using this setup I'm able to boot but as soon as I reinstall the kernel (therefore updating to 4.20.6) it freezes again.

Here some more information:
Failed boot log: https://pastebin.com/gYfr6UsC
I can't see the issue in there. The only thing I noticed is EXT4-fs (dm-3): re-mounted. Opts: discard,errors=remount-ro.

I saw no freeze in the log.
Are your sure it freezes ? How long did you wait ?  ssh login possible ?

A wild guess since you are using sddm: you are maybe running out of entropy ?

Re: [Solved] 4.20.6: Freeze during boot (before graphical interface)

At least it seems as it freezes. I can't switch to any other terminal and I can only turn the laptop off by holding the power button for 8s. I can't try SSH at the moment as I don't have another computer on the same network.

In the meantime I noticed that it seems to be caused by bumblebeed. If I disable the service I can boot just fine. Starting bumblebeed after the boot is done works fine. That's fine for me for the moment.
