Solaris Nevada build 20 (for which we are about to release the source
drop) has the following significant bug (6302583):
http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6302583
One side effect of the bug is that 64 bit systems (sparcv9/amd64) will
not be able to start X. Depending on your framebuffer, you will see
errour messages indicating errour trying to load microcode. Example:
gfb: no microcode loader registered
gfb: zfb_ucode_wait timeout
or
jfb: Waiting for microcode to load
The following fix should resolve the bug:
