One can recover from boot error by booting form live DVD/USB and 
repairing GRUB.

Try installing development packages in a zone if they are from userland.

Can error be associated with some illumos update or userland updates to 
isolate?

Do you use SATA disks on SATA controller or SAS expanders with using 
SATA disks or Expanders at all - all of this is not supported as I know.
Do you have ECC RAM?

What illumos is there etc.
I don't have XstreamOS installed at the moment to try to reproduce.

Maybe question is better for oi-dev but oi-discuss will be good enough 
for now.

krtld is part of 'developer/debug/mdb' package on OI. try reinstalling 
GRUB with new boot archive.
I had similar strange problem booting after some illumos update about 
year and a half ago, but not like this.
I couls only solve it by booting form Live DVD (and not even recent one 
but older, Opensolaris one as I remember) and reinstalling GRUB. After 
that reinstalling GRUB with newer ISOs worked OK..
