If you use Niagara (sun4v) machines, or any of the following platforms:

> SUNW,Ultra-1-Engine
> SUNW,UltraAX-MP
> SUNW,UltraAX-e
> SUNW,UltraAX-e2
> SUNW,UltraSPARC-IIi-Engine
> SUNW,UltraSPARC-IIi-cEngine
> SUNW,UltraSPARCengine_CP-20
> SUNW,UltraSPARCengine_CP-40
> SUNW,UltraSPARCengine_CP-60
> SUNW,UltraSPARCengine_CP-80

...then you SHOULD READ THIS NOTE.  Otherwise, do what you like.

Executive summary: DO NOT USE SOS10-built bits on the aforementioned
platforms.

Due to an unfortunate combination of

	6323803 compiler bug causes __*mul64 failure; svc.configd dies

and

	6324631 sparc hwmuldiv support should be in libc

and missing platform library links on the aforementioned machines, those
platforms are essentially unusable with onnv archives built after the
putback of

	6316914 changes in ON needed for Vulcan (SunStudio 10) compiler switch

on Wednesday, September 7.

How do you tell if you're affected?  You'll see the following error
message on boot:

> Executing last command: boot
> Boot device: /pci@1f,0/pci@1,1/scsi@2/disk@0,0:b  File and args:

What should you do?  Either bfu to the onnv_23 archives, or override the
following settings from usr/src/Makefile.master in your build environment:

> # Base directory where compilers are loaded.
> # Defined here so it can be overridden by developer.
> #
> SPRO_ROOT=		$(BUILD_TOOLS)/SUNWspro
> SPRO_VROOT=		$(SPRO_ROOT)/SOS10
> GNU_ROOT=		$(SFW_ROOT)

...in particular, set SPRO_VROOT to reference SOS8 instead of SOS10.

When will the madness stop?  Watch for a putback of

	6324631 sparc hwmuldiv support should be in libc

sometime before the close of build 24 (Monday night, Pacific time).
Once that makes it into the onnv nightly (or your workspace), you'll be
able to use the resulting archives.  You'll get another note when that
happens.

Many, many thanks to Jonathan Adams for his work root causing this
failure, and driving resolution on both the compiler and ON sides.
