When I ran the Software updater yesterday, a security update from kernel version 5.3.0-24-generic to 5.3.0-26-generic was installed. When I rebooted the system, I was dumped to the boot-loaders busy-box prompt. I tried also under the Advanced options for Linux where normal and recovery mode versions of both v5.3.0-26-generic and v5.3.0-24-generic were available. Both of the 5.3.0-26-generic options also sent me to the busy-box prompt. However, when I tried the 5.3.0-24-generic option I was able to get the system started, and it seems to work normally.

Some additional observations:

While watching the messages when trying to get the 5.3.0-26 version going I noticed that it was not able to find the file system for my Ubuntu-Mate installation.

I also noticed that the size of the initrd.img-5.3.0-26-generic is about 4 MBytes smaller than the initrd.img-5.3.0-24-generic.

Since the Ubuntu-Mate file system is in a LVM partition, I am wondering if the initrd.img-5.3.0-26-generic lacks the capability to see the LVM partition.

I have tried to figure out how to unpack the two initrd.img files to see what the differences are, but none of the information I have seen on the web about how to do this works on the Ubuntu versions of the file.

My computer is a Dell XPS-13-9370.
