4.4.0-108: stuck loading initial ramdisk

[Kolargol00]

This kernel does not boot on my machine: it stops at loading the ramdisk. The only information displayed is:

> Loading Linux 4.4.0-108-generic ...
> Loading initial ramdisk ...

I'd like to provide more information about what is happening (or not happening), but I don't know how to debug kernel boot. Any suggestions are welcome. :)

The previous kernel 4.4.0-104 works fine.

This may be a duplicate of bug 1741934, which was fixed by the 4.4.0-109 kernel. Can you upgrade to 4.4.0-109 and see if this bug still exists?

[Kolargol00 (kolargol00)]

My apologies for the very late reply. IIRC, the update to 4.4.0-109 did indeed fix this.
