I cant recall the PR number but this is in the send-pr database...
Someone created the entry nad I added to it..

It is to do with the setting of the atkbd flag in the GENERIC kernel
as supplied.  It has to be set to 0 for the Mitsubishi keyboards to have any 
hope of
working ... but in the GENERIC kernel from about 4.5?? it is set to 1. So on a 
new
install, you will get through the bootloader then die.........
Not being a kernel driver hacker.. I didnt/couldnt get any further.

The only workarounds for the Mitsubishi keyboards is dont use them. OR
install an early distro (4.5??), cvsup to -STABLE or wherver, edit the 
GENERIC configuration file and set the offending flag to 0, make world
and try again. (verrryyyy tedious... and could still bite you)

We got a batch of these keyboards some time ago at work and had to return
them all.
