Hey all,
I recently acquired a nice SS20 w/ dual Ross CPUs (RT620/625 @ 200MHz) 
and did a fresh 3.0 install w/ the GENERIC.MP kernel.  The system runs 
just fine however I'm trying to bump up the performance by rebuilding 
everything with the following (gleaned from various port-sparc posts) in 
/etc/mk.conf:

# cat /etc/mk.conf
CPUFLAGS=-mcpu=hypersparc
COPTS+=-pipe
BUILDFLAGS+=-j3

I've already built the toolchain and distribution per steps 2 & 3 in the 
"Tracking NetBSD-current: updating" document (please see below and/or 
http://www.netbsd.org/Documentation/current/#updating) but am having 
problems with building a kernel - even GENERIC / GENERIC.MP .  GENERIC 
and GENRIC.MP appear to build okay (no errors appear) however neither 
will actually boot (GENERIC.MP causes a Watchdog Reset; GENERIC actually 
hangs the system).  Both appear to get stuck right after the following 
dmesg output:
...
ms0 at zs1 channel 1: baud rate 1200

Not sure if that's actually meaningful of just a coincidence.  Anyways, 
reading through the port-sparc and other list archives suggests that on 
sparc a watchdog reset would be due to a kernel bug so maybe my mk.conf 
needs tweaking (I'm assuming that GENERIC/GENERIC.MP _are_ configured 
correctly since the system is currently running fine).  BTW, I'm working 
with the netbsd-3-0 src checked out Feb 26, 2006 via CVS.

Along similar lines, are the steps in "Tracking NetBSD-current: 
updating" appropriate and in the right order for what I want to do?
I'm pretty much following the document exactly except for the TOOLDIR 
and OBJDIR locations which are /var/usr/tools and /var/usr/obj respectively:

(from "Tracking NetBSD-current")

#1  From the root of the source tree:

$ cd /usr/src

#2 Build the toolchain:

$ ./build.sh -O ../obj -T ../tools -U -u tools

#3 Build the distribution:

$ ./build.sh  -O ../obj -T ../tools -U -u distribution

#4 Build the kernel:

$ ./build.sh  -O ../obj -T ../tools -U -u kernel=GENERIC

#5 Install the kernel:

     $ cd ../obj/sys/arch/<ARCH>/compile/GENERIC
     $ su
     # mv /netbsd /netbsd.old
     # cp netbsd /netbsd

#6 Reboot into the new kernel:

     # shutdown -r now

My current dmesg (GENERIC.MP kernel) is below for reference.

Cheers,
Jeff
