If you enable EARLY_CONSOLE, don't generate any Zilog SCC interrupts
before the pmac_zilog driver gets opened (i.e. before getty starts on
ttyS0). The early boot asm doesn't properly intialise the SCC
interrupts (known bug).
I don't know if it is related to this
Probably.
but after compiling the kernel 3.10.0-rc2 from Geert defconfig branch,
I'm able to boot close to the end of init level 2 and then my screen is
filled by "unexpected interrupt 112" and I can't do anything more.
I've seen it before, many years ago. I've not tested a Quadra 800 for 5
years or more, BTW.
This works if I disable "EARLY_PRINTK". To do that I need to patch Kconfig :
--- a/arch/m68k/Kconfig.debug
+++ b/arch/m68k/Kconfig.debug
@@ -11,7 +11,7 @@ config BOOTPARAM_STRING
depends on BOOTPARAM
config EARLY_PRINTK
- bool "Early printk" if EMBEDDED
+ bool "Early printk"
depends on MVME16x || MAC
default y
