Yes, I've been able to access a shell by adding "init=/bin/bash" on
the kernel command line.
The modules needed to calm down fans are : i2c-powermac and
windfarm_pm72 (this one triggers the others).
They are, of course, available in the ISO.
But what I don't understand is why they are available as modules
whereas they have been marked as 'y' (not 'm') in the config.
I guess this is because CONFIG_I2C is set to 'm' in config-generic.
You should set it to 'y' in config-powerpc64 (at least, like in
config-armv7-generic) to pull windfarm and i2c-powermac.Otherwise, I
think the i2c-powermac module is not automatically loaded by the
yeah, sounds reasonable, all arches (s390x disables it explicitly) are
setting CONFIG_I2C to Y, so it might get moved to config-generic. After
that the Y for WINDFARM_PM* modules will be in effect too. The kernel
configs need definitely some work, it is on our to-do list ...
