pmu intr 02 02
pmu_init: timed out acking intrs
Warning: no ADB interface detected
This appears to be the fundamental problem. For some reason, this
time it can't initialize the PMU properly. I suspect that if we
start to initialize the PMU but don't finish, it gets unhappy.
Ditch the pmu_intr printk message and it may be fine. That's what messes
up the timing (or messes up the interrupt level for a brief period,
perhaps).
The successful boot is only different by the arguments, not a
different kernel? It looks like the timing must change such that
the messages to the PMU get out of sync. These are the hard ones
to debug because adding extra code changes the behavior.
FWIW, I think the pmu intr 00 are one second timer interrupts from the PMU
- is that about the size of it, as judged from the number of interrupts
generated?
Anyway, same argument here - don't print these messages, they just mess up
PMU timing. Log them to procfs or sysfs instead.
Pretty amazing work, if I may say so - I had no idea the m68k powerbooks
actually work so well.
