Thanks, Arthur and Giocomon for the feedback.
I tried the suggestions but none of them worked. Let me give you more
information about each of them:
1) fs.py with older image:
same panic error as above.
2) fs.py with --bare-metal and --param 'system.highest_el_is_64 = True' (but no
--param 'system.auto_reset_addr_64 =
True'):

4) Trying --bare-metal with arm/starter_fs.py does not work because the script
does not expect that option. So I could not try if it helps.
5) I also downloaded a 32 bit image and pointed that (testing with both
arm/starter_fs.py and fs.py) and also pointing the vmlinux.arm (not arm64) and
had the same panic message.
I'll try to rollback to an older version and see if it works (and at which
commit things broke). In the meantime, further suggestions are welcome.
Thank you.
Pedro.
