Rats!
Can you send me the complete dmesg and .config for each kernel.
I'll poke at this whne I get to work on Monday.

When it works, do you have more than one processor assigned to the
partition?
I noticed something similar last last week. What I've narrowed down so
far, is that it only fails in a single-processor partition, (dedicated
or shared doesnt matter). if I assign another proc, the partition
boots as expected.
turning on initcall_debug, output to the console stops after we get as
far as hvc_vio_init().
a small sampling of register dumps show us in these places:
put_chars() calling spin_lock_irqsave()
put_chars() calling vio_get_event_buffer()
put_chars() calling vio_free_event_buffer()
spin_unlock_irqrestore() calling local_irq_restore()

The partition does not change, only the kernel (And iseries_defconfig) changes.
The partition has a single cpu assigned, 0.8 %
