This breaks booting on the PowerMac G5 (PowerMac7,3), there is a panic
somwhere in an irq.

Do you have more details ? Like at least the dump of the panic Oops ?

Can it be reproduced on QEMU ?

No, qemu does not support SMP.

Can you try "powersave=off" commandline to disable idlestate and
see if it boots?

Other call stacks are very likely not possible such as sched_balance_find_src_group
