I totally missed that I didn't have a debug build. My little script to
build Xen itself was broken, and wasn't setting 'debug=y'. This also
explains the bad Solaris panic stack (no frame pointer, and we expect
it). There was also another problem[1].

I'll reproduce in debug mode, and look some more at stuff around
shadow_set_l1e() as you suggest, and get back to you soon.

[1] because we don't want to get stuck, the Solaris panic path doesn't
take any locks, and that means no console_start_sync(), so we were
leaving the printk serial buffer unprinted.
