The message "Cannot patch isolinux boot image" is issued on
several occasions. Most of them would be accompanied by
messages other than you see.

I tested the two remaining candidates and only this one produces
matching error messages:

libisofs was told to prepare isohybrid but no boot image
was given. (-isohybrid-mbr without -b)

  xorriso -abort_on FATAL -report_about SORRY \
    -as mkisofs \
      -o test.iso \
      -isohybrid-mbr dummy.mbr \
      -print-size \
      some_directory

yields

  GNU xorriso 1.2.9 : RockRidge filesystem manipulator, libburnia project.

  libisofs: MISHAP : Cannot patch isolinux boot image
  xorriso : FAILURE : Failed to prepare session write run
  xorriso : SORRY : -print_size: Failed to set up virtual -commit


Whatever, the problem sits in the arguments for booting (or in
my handling of those arguments).
If possible i would like to see the output of a run with

  xorriso -abort_on FATAL -report_about ALL -as mkisofs ...

This would tell all program arguments and lots of other info.

This is the caller of xorriso being unhappy about the result.


Have a nice day :)
