The connection of ttyS0 to /dev/console doesnt seem to work anymore mit
2.6.15-rc5+6 on a POWER4 p630 in fullsystempartition mode, no HMC
connected. It works with 2.6.14.4.
I tested 2.6.15-rc6 arch/powerpc/configs/ppc64_defconfig.
Our SLES9 /init script in initramfs doesnt print anything with 2.6.15
after 'Freeing unused kernel memory: 360k freed'. But it does print its
banner with 2.6.14.4. Other system with hvc console appear to work,
like JS20 or some POWER5 boxes.
So this regression seems to be local to ttyS0. The bootlog shows that
the firmware stdout device is properly detected at "COM1".
I will try older rc kernels now, but I may lose remote control of the
system.
The system appears to boot a bit into the init scripts, as the (unknown)
TIOCGDEV ioctl indicates. sysrq is not recognized. Forcing the system
into xmon shows all cpus are idle. Triggering a sysrq t via PS/2
keyboard shows this:

It seems to have been broken a while: According to test.kernel.org (last
machine in the matrix is an SMP mode p650), it broke between 2.6.14-git2
and 2.6.14-git3. Console output can be found in:
http://test.kernel.org/15622/debug/console.log for the failed one
http://test.kernel.org/15530/debug/console.log for the successful one

I remember someone mentioned that a 43p 150 did not boot if the keyboard
is connected. Will try that tomorrow. The git2-3 diff is huge, so maybe
this hint helps.

Yes, removing the keyboard helps.

my bisect result doesnt make much sense. The bad one is

powerpc: Merge i8259.c into arch/powerpc/sysdev
This changes the parameters for i8259_init so that it takes two
parameters: a physical address for generating an interrupt
acknowledge cycle, and an interrupt number offset. i8259_init
now sets the irq_desc[] for its interrupts; all the callers
were doing this, and that code is gone now. This also defines
a CONFIG_PPC_I8259 symbol to select i8259.o for inclusion, and
makes the platforms that need it select that symbol.

Try this patch... it fixes things on the p630 at work.
