Have you tried booting illumos in verbose mode — edit the grub command line and provide ‘-v’.  That may give you a better backtrace than a program counter.

This error is from the UEFI code.  It implies that the CSM boot failed or was never invoked.  If the HDD isn’t bootable, yet the CD is, that is the most likely source as the CSM assumes the first block device it encounters is the desired boot source.
