LinuxQuestions.org - Squashfs filesystem could not be mounted error

Hello,

Attempting to install Gentoo (from a 05/08/2020 minimal install CD) on a Sun Ultra 5 SPARC system. Upon booting from the CD, I come across an error when the squashfs filesystem is attempted to mounted.

Code:

>> Determining looptype ...

>> Mounting squashfs filesystem

mount: mounting /dev/loop0 on /newroot/mnt/livecd failed: Invalid argument

!! Squashfs filesystem could not be mounted, dropping into shell.



>> Welcome to Genkernel 4.0.7 (2020-05-10 18:32:47 UTC) rescue shell!

>> ...running Linux kernel 5.4.38-gentoo-sparc64



rescueshell /newroot #

Could someone shed some light on what exactly could be failing or where I could find a log file that shows some more information about the issue?

My system specs of this Ultra 5:
270MHz UltraSPARC IIi
128MB RAM
20GB IDE hard drive
IDE CD-ROM drive

Thanks in advance,
Austin
