I have seen this happen as well; when trying to boot from san disks.
Do you have your root filesystem on a san disk? Can you post your user
direct entry for a user that fails?
When you logged all the way out of your Linux guests you reset that
user. A lot of different things could have happened at that point.
Do any of your Linux guests still work? When they boot do they go
straight to the
CPU errors? I am assuming you don't get the zipl boot menu.
One thing to look for is an overlaps in your disk map.
{from maint}
diskmap user {generates a new disk map}
x user diskmap {opens the new map in the wonderful z/os editor}
{then search for overlaps}
{I usually use "right 10" first so I can see the "gap' messages"}
/over
If you have an overlap that would be the issue.
Otherwise either you are not finding your disk at boot or your zipl
boot was corrupted.
If you a working system you can move the disk to the new system and
try to mount it from the working Linux , if it mounts then you can try
to rewire the zipl boot block.
